+# mousetrap
+
+mousetrap is a tiny library that answers a single question.
+
+On a Windows machine, was the process invoked by someone double clicking on
+the executable file while browsing in explorer?
+
+### Motivation
+
+Windows developers unfamiliar with command line tools will often "double-click"
+the executable for a tool. Because most CLI tools print the help and then exit
+when invoked without arguments, this is often very frustrating for those users.
+
+mousetrap provides a way to detect these invocations so that you can provide
+more helpful behavior and instructions on how to run the CLI tool. To see what
+this looks like, both from an organizational and a technical perspective, see
+https://inconshreveable.com/09-09-2014/sweat-the-small-stuff/
+
+### The interface
+
+The library exposes a single interface:
+
+    func StartedByExplorer() (bool)

+Blackfriday [![Build Status](https://travis-ci.org/russross/blackfriday.svg?branch=master)](https://travis-ci.org/russross/blackfriday)
+===========
+
+Blackfriday is a [Markdown][1] processor implemented in [Go][2]. It
+is paranoid about its input (so you can safely feed it user-supplied
+data), it is fast, it supports common extensions (tables, smart
+punctuation substitutions, etc.), and it is safe for all utf-8
+(unicode) input.
+
+HTML output is currently supported, along with Smartypants
+extensions. An experimental LaTeX output engine is also included.
+
+It started as a translation from C of [Sundown][3].
+
+
+Installation
+------------
+
+Blackfriday is compatible with Go 1. If you are using an older
+release of Go, consider using v1.1 of blackfriday, which was based
+on the last stable release of Go prior to Go 1. You can find it as a
+tagged commit on github.
+
+With Go 1 and git installed:
+
+    go get github.com/russross/blackfriday
+
+will download, compile, and install the package into your `$GOPATH`
+directory hierarchy. Alternatively, you can achieve the same if you
+import it into a project:
+
+    import "github.com/russross/blackfriday"
+
+and `go get` without parameters.
+
+Usage
+-----
+
+For basic usage, it is as simple as getting your input into a byte
+slice and calling:
+
+    output := blackfriday.MarkdownBasic(input)
+
+This renders it with no extensions enabled. To get a more useful
+feature set, use this instead:
+
+    output := blackfriday.MarkdownCommon(input)
+
+### Sanitize untrusted content
+
+Blackfriday itself does nothing to protect against malicious content. If you are
+dealing with user-supplied markdown, we recommend running blackfriday's output
+through HTML sanitizer such as
+[Bluemonday](https://github.com/microcosm-cc/bluemonday).
+
+Here's an example of simple usage of blackfriday together with bluemonday:
+
+``` go
+import (
+    "github.com/microcosm-cc/bluemonday"
+    "github.com/russross/blackfriday"
+)
+
+// ...
+unsafe := blackfriday.MarkdownCommon(input)
+html := bluemonday.UGCPolicy().SanitizeBytes(unsafe)
+```
+
+### Custom options
+
+If you want to customize the set of options, first get a renderer
+(currently either the HTML or LaTeX output engines), then use it to
+call the more general `Markdown` function. For examples, see the
+implementations of `MarkdownBasic` and `MarkdownCommon` in
+`markdown.go`.
+
+You can also check out `blackfriday-tool` for a more complete example
+of how to use it. Download and install it using:
+
+    go get github.com/russross/blackfriday-tool
+
+This is a simple command-line tool that allows you to process a
+markdown file using a standalone program.  You can also browse the
+source directly on github if you are just looking for some example
+code:
+
+* <http://github.com/russross/blackfriday-tool>
+
+Note that if you have not already done so, installing
+`blackfriday-tool` will be sufficient to download and install
+blackfriday in addition to the tool itself. The tool binary will be
+installed in `$GOPATH/bin`.  This is a statically-linked binary that
+can be copied to wherever you need it without worrying about
+dependencies and library versions.
+
+
+Features
+--------
+
+All features of Sundown are supported, including:
+
+*   **Compatibility**. The Markdown v1.0.3 test suite passes with
+    the `--tidy` option.  Without `--tidy`, the differences are
+    mostly in whitespace and entity escaping, where blackfriday is
+    more consistent and cleaner.
+
+*   **Common extensions**, including table support, fenced code
+    blocks, autolinks, strikethroughs, non-strict emphasis, etc.
+
+*   **Safety**. Blackfriday is paranoid when parsing, making it safe
+    to feed untrusted user input without fear of bad things
+    happening. The test suite stress tests this and there are no
+    known inputs that make it crash.  If you find one, please let me
+    know and send me the input that does it.
+
+    NOTE: "safety" in this context means *runtime safety only*. In order to
+    protect yourself agains JavaScript injection in untrusted content, see
+    [this example](https://github.com/russross/blackfriday#sanitize-untrusted-content).
+
+*   **Fast processing**. It is fast enough to render on-demand in
+    most web applications without having to cache the output.
+
+*   **Thread safety**. You can run multiple parsers in different
+    goroutines without ill effect. There is no dependence on global
+    shared state.
+
+*   **Minimal dependencies**. Blackfriday only depends on standard
+    library packages in Go. The source code is pretty
+    self-contained, so it is easy to add to any project, including
+    Google App Engine projects.
+
+*   **Standards compliant**. Output successfully validates using the
+    W3C validation tool for HTML 4.01 and XHTML 1.0 Transitional.
+
+
+Extensions
+----------
+
+In addition to the standard markdown syntax, this package
+implements the following extensions:
+
+*   **Intra-word emphasis supression**. The `_` character is
+    commonly used inside words when discussing code, so having
+    markdown interpret it as an emphasis command is usually the
+    wrong thing. Blackfriday lets you treat all emphasis markers as
+    normal characters when they occur inside a word.
+
+*   **Tables**. Tables can be created by drawing them in the input
+    using a simple syntax:
+
+    ```
+    Name    | Age
+    --------|------
+    Bob     | 27
+    Alice   | 23
+    ```
+
+*   **Fenced code blocks**. In addition to the normal 4-space
+    indentation to mark code blocks, you can explicitly mark them
+    and supply a language (to make syntax highlighting simple). Just
+    mark it like this:
+
+        ``` go
+        func getTrue() bool {
+            return true
+        }
+        ```
+
+    You can use 3 or more backticks to mark the beginning of the
+    block, and the same number to mark the end of the block.
+
+*   **Definition lists**. A simple definition list is made of a single-line
+    term followed by a colon and the definition for that term.
+
+        Cat
+        : Fluffy animal everyone likes
+        
+        Internet
+        : Vector of transmission for pictures of cats
+
+    Terms must be separated from the previous definition by a blank line.
+
+*   **Footnotes**. A marker in the text that will become a superscript number;
+    a footnote definition that will be placed in a list of footnotes at the
+    end of the document. A footnote looks like this:
+
+        This is a footnote.[^1]
+        
+        [^1]: the footnote text.
+
+*   **Autolinking**. Blackfriday can find URLs that have not been
+    explicitly marked as links and turn them into links.
+
+*   **Strikethrough**. Use two tildes (`~~`) to mark text that
+    should be crossed out.
+
+*   **Hard line breaks**. With this extension enabled (it is off by
+    default in the `MarkdownBasic` and `MarkdownCommon` convenience
+    functions), newlines in the input translate into line breaks in
+    the output.
+
+*   **Smart quotes**. Smartypants-style punctuation substitution is
+    supported, turning normal double- and single-quote marks into
+    curly quotes, etc.
+
+*   **LaTeX-style dash parsing** is an additional option, where `--`
+    is translated into `&ndash;`, and `---` is translated into
+    `&mdash;`. This differs from most smartypants processors, which
+    turn a single hyphen into an ndash and a double hyphen into an
+    mdash.
+
+*   **Smart fractions**, where anything that looks like a fraction
+    is translated into suitable HTML (instead of just a few special
+    cases like most smartypant processors). For example, `4/5`
+    becomes `<sup>4</sup>&frasl;<sub>5</sub>`, which renders as
+    <sup>4</sup>&frasl;<sub>5</sub>.
+
+
+Other renderers
+---------------
+
+Blackfriday is structured to allow alternative rendering engines. Here
+are a few of note:
+
+*   [github_flavored_markdown](https://godoc.org/github.com/shurcooL/github_flavored_markdown):
+    provides a GitHub Flavored Markdown renderer with fenced code block
+    highlighting, clickable header anchor links.
+
+    It's not customizable, and its goal is to produce HTML output
+    equivalent to the [GitHub Markdown API endpoint](https://developer.github.com/v3/markdown/#render-a-markdown-document-in-raw-mode),
+    except the rendering is performed locally.
+
+*   [markdownfmt](https://github.com/shurcooL/markdownfmt): like gofmt,
+    but for markdown.
+
+*   LaTeX output: renders output as LaTeX. This is currently part of the
+    main Blackfriday repository, but may be split into its own project
+    in the future. If you are interested in owning and maintaining the
+    LaTeX output component, please be in touch.
+
+    It renders some basic documents, but is only experimental at this
+    point. In particular, it does not do any inline escaping, so input
+    that happens to look like LaTeX code will be passed through without
+    modification.
+    
+*   [Md2Vim](https://github.com/FooSoft/md2vim): transforms markdown files into vimdoc format.
+
+
+Todo
+----
+
+*   More unit testing
+*   Improve unicode support. It does not understand all unicode
+    rules (about what constitutes a letter, a punctuation symbol,
+    etc.), so it may fail to detect word boundaries correctly in
+    some instances. It is safe on all utf-8 input.

+<h2>Getting the Gist of Markdown's Formatting Syntax</h2>
+
+<p>This page offers a brief overview of what it's like to use Markdown.
+The <a href="/projects/markdown/syntax" title="Markdown Syntax">syntax page</a> provides complete, detailed documentation for
+every feature, but Markdown should be very easy to pick up simply by
+looking at a few examples of it in action. The examples on this page
+are written in a before/after style, showing example syntax and the
+HTML output produced by Markdown.</p>
+
+<p>It's also helpful to simply try Markdown out; the <a href="/projects/markdown/dingus" title="Markdown Dingus">Dingus</a> is a
+web application that allows you type your own Markdown-formatted text
+and translate it to XHTML.</p>
+
+<p><strong>Note:</strong> This document is itself written using Markdown; you
+can <a href="/projects/markdown/basics.text">see the source for it by adding '.text' to the URL</a>.</p>
+
+<h2>Paragraphs, Headers, Blockquotes</h2>
+
+<p>A paragraph is simply one or more consecutive lines of text, separated
+by one or more blank lines. (A blank line is any line that looks like a
+blank line -- a line containing nothing spaces or tabs is considered
+blank.) Normal paragraphs should not be intended with spaces or tabs.</p>
+
+<p>Markdown offers two styles of headers: <em>Setext</em> and <em>atx</em>.
+Setext-style headers for <code>&lt;h1&gt;</code> and <code>&lt;h2&gt;</code> are created by
+&quot;underlining&quot; with equal signs (<code>=</code>) and hyphens (<code>-</code>), respectively.
+To create an atx-style header, you put 1-6 hash marks (<code>#</code>) at the
+beginning of the line -- the number of hashes equals the resulting
+HTML header level.</p>
+
+<p>Blockquotes are indicated using email-style '<code>&gt;</code>' angle brackets.</p>
+
+<p>Markdown:</p>
+
+<pre><code>A First Level Header
+====================
+
+A Second Level Header
+---------------------
+
+Now is the time for all good men to come to
+the aid of their country. This is just a
+regular paragraph.
+
+The quick brown fox jumped over the lazy
+dog's back.
+
+### Header 3
+
+&gt; This is a blockquote.
+&gt; 
+&gt; This is the second paragraph in the blockquote.
+&gt;
+&gt; ## This is an H2 in a blockquote
+</code></pre>
+
+<p>Output:</p>
+
+<pre><code>&lt;h1&gt;A First Level Header&lt;/h1&gt;
+
+&lt;h2&gt;A Second Level Header&lt;/h2&gt;
+
+&lt;p&gt;Now is the time for all good men to come to
+the aid of their country. This is just a
+regular paragraph.&lt;/p&gt;
+
+&lt;p&gt;The quick brown fox jumped over the lazy
+dog's back.&lt;/p&gt;
+
+&lt;h3&gt;Header 3&lt;/h3&gt;
+
+&lt;blockquote&gt;
+    &lt;p&gt;This is a blockquote.&lt;/p&gt;
+
+    &lt;p&gt;This is the second paragraph in the blockquote.&lt;/p&gt;
+
+    &lt;h2&gt;This is an H2 in a blockquote&lt;/h2&gt;
+&lt;/blockquote&gt;
+</code></pre>
+
+<h3>Phrase Emphasis</h3>
+
+<p>Markdown uses asterisks and underscores to indicate spans of emphasis.</p>
+
+<p>Markdown:</p>
+
+<pre><code>Some of these words *are emphasized*.
+Some of these words _are emphasized also_.
+
+Use two asterisks for **strong emphasis**.
+Or, if you prefer, __use two underscores instead__.
+</code></pre>
+
+<p>Output:</p>
+
+<pre><code>&lt;p&gt;Some of these words &lt;em&gt;are emphasized&lt;/em&gt;.
+Some of these words &lt;em&gt;are emphasized also&lt;/em&gt;.&lt;/p&gt;
+
+&lt;p&gt;Use two asterisks for &lt;strong&gt;strong emphasis&lt;/strong&gt;.
+Or, if you prefer, &lt;strong&gt;use two underscores instead&lt;/strong&gt;.&lt;/p&gt;
+</code></pre>
+
+<h2>Lists</h2>
+
+<p>Unordered (bulleted) lists use asterisks, pluses, and hyphens (<code>*</code>,
+<code>+</code>, and <code>-</code>) as list markers. These three markers are
+interchangable; this:</p>
+
+<pre><code>*   Candy.
+*   Gum.
+*   Booze.
+</code></pre>
+
+<p>this:</p>
+
+<pre><code>+   Candy.
++   Gum.
++   Booze.
+</code></pre>
+
+<p>and this:</p>
+
+<pre><code>-   Candy.
+-   Gum.
+-   Booze.
+</code></pre>
+
+<p>all produce the same output:</p>
+
+<pre><code>&lt;ul&gt;
+&lt;li&gt;Candy.&lt;/li&gt;
+&lt;li&gt;Gum.&lt;/li&gt;
+&lt;li&gt;Booze.&lt;/li&gt;
+&lt;/ul&gt;
+</code></pre>
+
+<p>Ordered (numbered) lists use regular numbers, followed by periods, as
+list markers:</p>
+
+<pre><code>1.  Red
+2.  Green
+3.  Blue
+</code></pre>
+
+<p>Output:</p>
+
+<pre><code>&lt;ol&gt;
+&lt;li&gt;Red&lt;/li&gt;
+&lt;li&gt;Green&lt;/li&gt;
+&lt;li&gt;Blue&lt;/li&gt;
+&lt;/ol&gt;
+</code></pre>
+
+<p>If you put blank lines between items, you'll get <code>&lt;p&gt;</code> tags for the
+list item text. You can create multi-paragraph list items by indenting
+the paragraphs by 4 spaces or 1 tab:</p>
+
+<pre><code>*   A list item.
+
+    With multiple paragraphs.
+
+*   Another item in the list.
+</code></pre>
+
+<p>Output:</p>
+
+<pre><code>&lt;ul&gt;
+&lt;li&gt;&lt;p&gt;A list item.&lt;/p&gt;
+&lt;p&gt;With multiple paragraphs.&lt;/p&gt;&lt;/li&gt;
+&lt;li&gt;&lt;p&gt;Another item in the list.&lt;/p&gt;&lt;/li&gt;
+&lt;/ul&gt;
+</code></pre>
+
+<h3>Links</h3>
+
+<p>Markdown supports two styles for creating links: <em>inline</em> and
+<em>reference</em>. With both styles, you use square brackets to delimit the
+text you want to turn into a link.</p>
+
+<p>Inline-style links use parentheses immediately after the link text.
+For example:</p>
+
+<pre><code>This is an [example link](http://example.com/).
+</code></pre>
+
+<p>Output:</p>
+
+<pre><code>&lt;p&gt;This is an &lt;a href=&quot;http://example.com/&quot;&gt;
+example link&lt;/a&gt;.&lt;/p&gt;
+</code></pre>
+
+<p>Optionally, you may include a title attribute in the parentheses:</p>
+
+<pre><code>This is an [example link](http://example.com/ &quot;With a Title&quot;).
+</code></pre>
+
+<p>Output:</p>
+
+<pre><code>&lt;p&gt;This is an &lt;a href=&quot;http://example.com/&quot; title=&quot;With a Title&quot;&gt;
+example link&lt;/a&gt;.&lt;/p&gt;
+</code></pre>
+
+<p>Reference-style links allow you to refer to your links by names, which
+you define elsewhere in your document:</p>
+
+<pre><code>I get 10 times more traffic from [Google][1] than from
+[Yahoo][2] or [MSN][3].
+
+[1]: http://google.com/        &quot;Google&quot;
+[2]: http://search.yahoo.com/  &quot;Yahoo Search&quot;
+[3]: http://search.msn.com/    &quot;MSN Search&quot;
+</code></pre>
+
+<p>Output:</p>
+
+<pre><code>&lt;p&gt;I get 10 times more traffic from &lt;a href=&quot;http://google.com/&quot;

+title=&quot;MSN Search&quot;&gt;MSN&lt;/a&gt;.&lt;/p&gt;
+</code></pre>
+
+<p>The title attribute is optional. Link names may contain letters,
+numbers and spaces, but are <em>not</em> case sensitive:</p>
+
+<pre><code>I start my morning with a cup of coffee and
+[The New York Times][NY Times].
+

+&lt;a href=&quot;http://www.nytimes.com/&quot;&gt;The New York Times&lt;/a&gt;.&lt;/p&gt;
+</code></pre>
+
+<h3>Images</h3>
+
+<p>Image syntax is very much like link syntax.</p>
+
+<p>Inline (titles are optional):</p>
+
+<pre><code>![alt text](/path/to/img.jpg &quot;Title&quot;)

+
+<p>Reference-style:</p>
+
+<pre><code>![alt text][id]
+

+</code></pre>
+
+<p>Both of the above examples produce the same output:</p>
+
+<pre><code>&lt;img src=&quot;/path/to/img.jpg&quot; alt=&quot;alt text&quot; title=&quot;Title&quot; /&gt;
+</code></pre>
+
+<h3>Code</h3>
+
+<p>In a regular paragraph, you can create code span by wrapping text in
+backtick quotes. Any ampersands (<code>&amp;</code>) and angle brackets (<code>&lt;</code> or
+<code>&gt;</code>) will automatically be translated into HTML entities. This makes
+it easy to use Markdown to write about HTML example code:</p>
+
+<pre><code>I strongly recommend against using any `&lt;blink&gt;` tags.
+
+I wish SmartyPants used named entities like `&amp;mdash;`
+instead of decimal-encoded entites like `&amp;#8212;`.

+
+Getting the Gist of Markdown's Formatting Syntax
+------------------------------------------------
+
+This page offers a brief overview of what it's like to use Markdown.
+The [syntax page] [s] provides complete, detailed documentation for
+every feature, but Markdown should be very easy to pick up simply by
+looking at a few examples of it in action. The examples on this page
+are written in a before/after style, showing example syntax and the
+HTML output produced by Markdown.
+
+It's also helpful to simply try Markdown out; the [Dingus] [d] is a
+web application that allows you type your own Markdown-formatted text
+and translate it to XHTML.
+
+**Note:** This document is itself written using Markdown; you
+can [see the source for it by adding '.text' to the URL] [src].
+
+  [s]: /projects/markdown/syntax  "Markdown Syntax"

+
+
+## Paragraphs, Headers, Blockquotes ##
+
+A paragraph is simply one or more consecutive lines of text, separated
+by one or more blank lines. (A blank line is any line that looks like a
+blank line -- a line containing nothing spaces or tabs is considered
+blank.) Normal paragraphs should not be intended with spaces or tabs.
+
+Markdown offers two styles of headers: *Setext* and *atx*.
+Setext-style headers for `<h1>` and `<h2>` are created by
+"underlining" with equal signs (`=`) and hyphens (`-`), respectively.
+To create an atx-style header, you put 1-6 hash marks (`#`) at the
+beginning of the line -- the number of hashes equals the resulting
+HTML header level.
+
+Blockquotes are indicated using email-style '`>`' angle brackets.
+
+Markdown:
+
+    A First Level Header
+    ====================
+    
+    A Second Level Header
+    ---------------------
+
+    Now is the time for all good men to come to
+    the aid of their country. This is just a
+    regular paragraph.
+
+    The quick brown fox jumped over the lazy
+    dog's back.
+    
+    ### Header 3
+
+    > This is a blockquote.
+    > 
+    > This is the second paragraph in the blockquote.
+    >
+    > ## This is an H2 in a blockquote
+
+
+Output:
+
+    <h1>A First Level Header</h1>
+    
+    <h2>A Second Level Header</h2>
+    
+    <p>Now is the time for all good men to come to
+    the aid of their country. This is just a
+    regular paragraph.</p>
+    
+    <p>The quick brown fox jumped over the lazy
+    dog's back.</p>
+    
+    <h3>Header 3</h3>
+    
+    <blockquote>
+        <p>This is a blockquote.</p>
+        
+        <p>This is the second paragraph in the blockquote.</p>
+        
+        <h2>This is an H2 in a blockquote</h2>
+    </blockquote>
+
+
+
+### Phrase Emphasis ###
+
+Markdown uses asterisks and underscores to indicate spans of emphasis.
+
+Markdown:
+
+    Some of these words *are emphasized*.
+    Some of these words _are emphasized also_.
+    
+    Use two asterisks for **strong emphasis**.
+    Or, if you prefer, __use two underscores instead__.
+
+Output:
+
+    <p>Some of these words <em>are emphasized</em>.
+    Some of these words <em>are emphasized also</em>.</p>
+    
+    <p>Use two asterisks for <strong>strong emphasis</strong>.
+    Or, if you prefer, <strong>use two underscores instead</strong>.</p>
+   
+
+
+## Lists ##
+
+Unordered (bulleted) lists use asterisks, pluses, and hyphens (`*`,
+`+`, and `-`) as list markers. These three markers are
+interchangable; this:
+
+    *   Candy.
+    *   Gum.
+    *   Booze.
+
+this:
+
+    +   Candy.
+    +   Gum.
+    +   Booze.
+
+and this:
+
+    -   Candy.
+    -   Gum.
+    -   Booze.
+
+all produce the same output:
+
+    <ul>
+    <li>Candy.</li>
+    <li>Gum.</li>
+    <li>Booze.</li>
+    </ul>
+
+Ordered (numbered) lists use regular numbers, followed by periods, as
+list markers:
+
+    1.  Red
+    2.  Green
+    3.  Blue
+
+Output:
+
+    <ol>
+    <li>Red</li>
+    <li>Green</li>
+    <li>Blue</li>
+    </ol>
+
+If you put blank lines between items, you'll get `<p>` tags for the
+list item text. You can create multi-paragraph list items by indenting
+the paragraphs by 4 spaces or 1 tab:
+
+    *   A list item.
+    
+        With multiple paragraphs.
+
+    *   Another item in the list.
+
+Output:
+
+    <ul>
+    <li><p>A list item.</p>
+    <p>With multiple paragraphs.</p></li>
+    <li><p>Another item in the list.</p></li>
+    </ul>
+    
+
+
+### Links ###
+
+Markdown supports two styles for creating links: *inline* and
+*reference*. With both styles, you use square brackets to delimit the
+text you want to turn into a link.
+
+Inline-style links use parentheses immediately after the link text.
+For example:
+
+    This is an [example link](http://example.com/).
+
+Output:
+
+    <p>This is an <a href="http://example.com/">
+    example link</a>.</p>
+
+Optionally, you may include a title attribute in the parentheses:
+
+    This is an [example link](http://example.com/ "With a Title").
+
+Output:
+
+    <p>This is an <a href="http://example.com/" title="With a Title">
+    example link</a>.</p>
+
+Reference-style links allow you to refer to your links by names, which
+you define elsewhere in your document:
+
+    I get 10 times more traffic from [Google][1] than from
+    [Yahoo][2] or [MSN][3].
+
+    [1]: http://google.com/        "Google"
+    [2]: http://search.yahoo.com/  "Yahoo Search"
+    [3]: http://search.msn.com/    "MSN Search"
+
+Output:
+
+    <p>I get 10 times more traffic from <a href="http://google.com/"
+    title="Google">Google</a> than from <a href="http://search.yahoo.com/"
+    title="Yahoo Search">Yahoo</a> or <a href="http://search.msn.com/"
+    title="MSN Search">MSN</a>.</p>
+
+The title attribute is optional. Link names may contain letters,
+numbers and spaces, but are *not* case sensitive:
+
+    I start my morning with a cup of coffee and
+    [The New York Times][NY Times].
+
+    [ny times]: http://www.nytimes.com/
+
+Output:
+
+    <p>I start my morning with a cup of coffee and
+    <a href="http://www.nytimes.com/">The New York Times</a>.</p>
+
+
+### Images ###
+
+Image syntax is very much like link syntax.
+
+Inline (titles are optional):
+
+    ![alt text](/path/to/img.jpg "Title")
+
+Reference-style:
+
+    ![alt text][id]
+
+    [id]: /path/to/img.jpg "Title"
+
+Both of the above examples produce the same output:
+
+    <img src="/path/to/img.jpg" alt="alt text" title="Title" />
+
+
+
+### Code ###
+
+In a regular paragraph, you can create code span by wrapping text in
+backtick quotes. Any ampersands (`&`) and angle brackets (`<` or
+`>`) will automatically be translated into HTML entities. This makes
+it easy to use Markdown to write about HTML example code:
+
+    I strongly recommend against using any `<blink>` tags.
+
+    I wish SmartyPants used named entities like `&mdash;`
+    instead of decimal-encoded entites like `&#8212;`.
+
+Output:
+
+    <p>I strongly recommend against using any
+    <code>&lt;blink&gt;</code> tags.</p>
+    
+    <p>I wish SmartyPants used named entities like
+    <code>&amp;mdash;</code> instead of decimal-encoded
+    entites like <code>&amp;#8212;</code>.</p>
+
+
+To specify an entire block of pre-formatted code, indent every line of
+the block by 4 spaces or 1 tab. Just like with code spans, `&`, `<`,
+and `>` characters will be escaped automatically.
+
+Markdown:
+
+    If you want your page to validate under XHTML 1.0 Strict,
+    you've got to put paragraph tags in your blockquotes:
+
+        <blockquote>
+            <p>For example.</p>
+        </blockquote>
+
+Output:
+
+    <p>If you want your page to validate under XHTML 1.0 Strict,
+    you've got to put paragraph tags in your blockquotes:</p>
+    
+    <pre><code>&lt;blockquote&gt;

+    &lt;/blockquote&gt;

+
+<h2 id="overview">Overview</h2>
+
+<h3 id="philosophy">Philosophy</h3>
+
+<p>Markdown is intended to be as easy-to-read and easy-to-write as is feasible.</p>
+
+<p>Readability, however, is emphasized above all else. A Markdown-formatted
+document should be publishable as-is, as plain text, without looking
+like it's been marked up with tags or formatting instructions. While
+Markdown's syntax has been influenced by several existing text-to-HTML
+filters -- including <a href="http://docutils.sourceforge.net/mirror/setext.html">Setext</a>, <a href="http://www.aaronsw.com/2002/atx/">atx</a>, <a href="http://textism.com/tools/textile/">Textile</a>, <a href="http://docutils.sourceforge.net/rst.html">reStructuredText</a>,
+<a href="http://www.triptico.com/software/grutatxt.html">Grutatext</a>, and <a href="http://ettext.taint.org/doc/">EtText</a> -- the single biggest source of
+inspiration for Markdown's syntax is the format of plain text email.</p>
+
+<p>To this end, Markdown's syntax is comprised entirely of punctuation
+characters, which punctuation characters have been carefully chosen so
+as to look like what they mean. E.g., asterisks around a word actually
+look like *emphasis*. Markdown lists look like, well, lists. Even
+blockquotes look like quoted passages of text, assuming you've ever
+used email.</p>
+
+<h3 id="html">Inline HTML</h3>
+
+<p>Markdown's syntax is intended for one purpose: to be used as a
+format for <em>writing</em> for the web.</p>
+
+<p>Markdown is not a replacement for HTML, or even close to it. Its
+syntax is very small, corresponding only to a very small subset of
+HTML tags. The idea is <em>not</em> to create a syntax that makes it easier
+to insert HTML tags. In my opinion, HTML tags are already easy to
+insert. The idea for Markdown is to make it easy to read, write, and
+edit prose. HTML is a <em>publishing</em> format; Markdown is a <em>writing</em>
+format. Thus, Markdown's formatting syntax only addresses issues that
+can be conveyed in plain text.</p>
+
+<p>For any markup that is not covered by Markdown's syntax, you simply
+use HTML itself. There's no need to preface it or delimit it to
+indicate that you're switching from Markdown to HTML; you just use
+the tags.</p>
+
+<p>The only restrictions are that block-level HTML elements -- e.g. <code>&lt;div&gt;</code>,
+<code>&lt;table&gt;</code>, <code>&lt;pre&gt;</code>, <code>&lt;p&gt;</code>, etc. -- must be separated from surrounding
+content by blank lines, and the start and end tags of the block should
+not be indented with tabs or spaces. Markdown is smart enough not
+to add extra (unwanted) <code>&lt;p&gt;</code> tags around HTML block-level tags.</p>
+
+<p>For example, to add an HTML table to a Markdown article:</p>
+
+<pre><code>This is a regular paragraph.
+
+&lt;table&gt;
+    &lt;tr&gt;
+        &lt;td&gt;Foo&lt;/td&gt;
+    &lt;/tr&gt;
+&lt;/table&gt;
+
+This is another regular paragraph.
+</code></pre>
+
+<p>Note that Markdown formatting syntax is not processed within block-level
+HTML tags. E.g., you can't use Markdown-style <code>*emphasis*</code> inside an
+HTML block.</p>
+
+<p>Span-level HTML tags -- e.g. <code>&lt;span&gt;</code>, <code>&lt;cite&gt;</code>, or <code>&lt;del&gt;</code> -- can be
+used anywhere in a Markdown paragraph, list item, or header. If you
+want, you can even use HTML tags instead of Markdown formatting; e.g. if
+you'd prefer to use HTML <code>&lt;a&gt;</code> or <code>&lt;img&gt;</code> tags instead of Markdown's
+link or image syntax, go right ahead.</p>
+
+<p>Unlike block-level HTML tags, Markdown syntax <em>is</em> processed within
+span-level tags.</p>
+
+<h3 id="autoescape">Automatic Escaping for Special Characters</h3>
+
+<p>In HTML, there are two characters that demand special treatment: <code>&lt;</code>
+and <code>&amp;</code>. Left angle brackets are used to start tags; ampersands are
+used to denote HTML entities. If you want to use them as literal
+characters, you must escape them as entities, e.g. <code>&amp;lt;</code>, and
+<code>&amp;amp;</code>.</p>
+
+<p>Ampersands in particular are bedeviling for web writers. If you want to
+write about 'AT&amp;T', you need to write '<code>AT&amp;amp;T</code>'. You even need to
+escape ampersands within URLs. Thus, if you want to link to:</p>
+
+<pre><code>http://images.google.com/images?num=30&amp;q=larry+bird
+</code></pre>
+
+<p>you need to encode the URL as:</p>
+
+<pre><code>http://images.google.com/images?num=30&amp;amp;q=larry+bird
+</code></pre>
+
+<p>in your anchor tag <code>href</code> attribute. Needless to say, this is easy to
+forget, and is probably the single most common source of HTML validation
+errors in otherwise well-marked-up web sites.</p>
+
+<p>Markdown allows you to use these characters naturally, taking care of
+all the necessary escaping for you. If you use an ampersand as part of
+an HTML entity, it remains unchanged; otherwise it will be translated
+into <code>&amp;amp;</code>.</p>
+
+<p>So, if you want to include a copyright symbol in your article, you can write:</p>
+
+<pre><code>&amp;copy;
+</code></pre>
+
+<p>and Markdown will leave it alone. But if you write:</p>
+
+<pre><code>AT&amp;T
+</code></pre>
+
+<p>Markdown will translate it to:</p>
+
+<pre><code>AT&amp;amp;T
+</code></pre>
+
+<p>Similarly, because Markdown supports <a href="#html">inline HTML</a>, if you use
+angle brackets as delimiters for HTML tags, Markdown will treat them as
+such. But if you write:</p>
+
+<pre><code>4 &lt; 5
+</code></pre>
+
+<p>Markdown will translate it to:</p>
+
+<pre><code>4 &amp;lt; 5
+</code></pre>
+
+<p>However, inside Markdown code spans and blocks, angle brackets and
+ampersands are <em>always</em> encoded automatically. This makes it easy to use
+Markdown to write about HTML code. (As opposed to raw HTML, which is a
+terrible format for writing about HTML syntax, because every single <code>&lt;</code>
+and <code>&amp;</code> in your example code needs to be escaped.)</p>
+
+<hr>
+
+<h2 id="block">Block Elements</h2>
+
+<h3 id="p">Paragraphs and Line Breaks</h3>
+
+<p>A paragraph is simply one or more consecutive lines of text, separated
+by one or more blank lines. (A blank line is any line that looks like a
+blank line -- a line containing nothing but spaces or tabs is considered
+blank.) Normal paragraphs should not be intended with spaces or tabs.</p>
+
+<p>The implication of the &quot;one or more consecutive lines of text&quot; rule is
+that Markdown supports &quot;hard-wrapped&quot; text paragraphs. This differs
+significantly from most other text-to-HTML formatters (including Movable
+Type's &quot;Convert Line Breaks&quot; option) which translate every line break
+character in a paragraph into a <code>&lt;br /&gt;</code> tag.</p>
+
+<p>When you <em>do</em> want to insert a <code>&lt;br /&gt;</code> break tag using Markdown, you
+end a line with two or more spaces, then type return.</p>
+
+<p>Yes, this takes a tad more effort to create a <code>&lt;br /&gt;</code>, but a simplistic
+&quot;every line break is a <code>&lt;br /&gt;</code>&quot; rule wouldn't work for Markdown.
+Markdown's email-style <a href="#blockquote">blockquoting</a> and multi-paragraph <a href="#list">list items</a>
+work best -- and look better -- when you format them with hard breaks.</p>
+
+<h3 id="header">Headers</h3>
+
+<p>Markdown supports two styles of headers, <a href="http://docutils.sourceforge.net/mirror/setext.html">Setext</a> and <a href="http://www.aaronsw.com/2002/atx/">atx</a>.</p>
+
+<p>Setext-style headers are &quot;underlined&quot; using equal signs (for first-level
+headers) and dashes (for second-level headers). For example:</p>
+
+<pre><code>This is an H1
+=============
+
+This is an H2
+-------------
+</code></pre>
+
+<p>Any number of underlining <code>=</code>'s or <code>-</code>'s will work.</p>
+
+<p>Atx-style headers use 1-6 hash characters at the start of the line,
+corresponding to header levels 1-6. For example:</p>
+
+<pre><code># This is an H1
+
+## This is an H2
+
+###### This is an H6
+</code></pre>
+
+<p>Optionally, you may &quot;close&quot; atx-style headers. This is purely
+cosmetic -- you can use this if you think it looks better. The
+closing hashes don't even need to match the number of hashes
+used to open the header. (The number of opening hashes
+determines the header level.) :</p>
+
+<pre><code># This is an H1 #
+
+## This is an H2 ##
+
+### This is an H3 ######

+<h3 id="blockquote">Blockquotes</h3>
+
+<p>Markdown uses email-style <code>&gt;</code> characters for blockquoting. If you're
+familiar with quoting passages of text in an email message, then you
+know how to create a blockquote in Markdown. It looks best if you hard
+wrap the text and put a <code>&gt;</code> before every line:</p>
+
+<pre><code>&gt; This is a blockquote with two paragraphs. Lorem ipsum dolor sit amet,
+&gt; consectetuer adipiscing elit. Aliquam hendrerit mi posuere lectus.
+&gt; Vestibulum enim wisi, viverra nec, fringilla in, laoreet vitae, risus.
+&gt; 
+&gt; Donec sit amet nisl. Aliquam semper ipsum sit amet velit. Suspendisse
+&gt; id sem consectetuer libero luctus adipiscing.
+</code></pre>
+
+<p>Markdown allows you to be lazy and only put the <code>&gt;</code> before the first
+line of a hard-wrapped paragraph:</p>
+
+<pre><code>&gt; This is a blockquote with two paragraphs. Lorem ipsum dolor sit amet,
+consectetuer adipiscing elit. Aliquam hendrerit mi posuere lectus.
+Vestibulum enim wisi, viverra nec, fringilla in, laoreet vitae, risus.
+
+&gt; Donec sit amet nisl. Aliquam semper ipsum sit amet velit. Suspendisse
+id sem consectetuer libero luctus adipiscing.
+</code></pre>
+
+<p>Blockquotes can be nested (i.e. a blockquote-in-a-blockquote) by
+adding additional levels of <code>&gt;</code>:</p>
+
+<pre><code>&gt; This is the first level of quoting.
+&gt;
+&gt; &gt; This is nested blockquote.
+&gt;
+&gt; Back to the first level.
+</code></pre>
+
+<p>Blockquotes can contain other Markdown elements, including headers, lists,
+and code blocks:</p>
+
+<pre><code>&gt; ## This is a header.
+&gt; 
+&gt; 1.   This is the first list item.
+&gt; 2.   This is the second list item.
+&gt; 
+&gt; Here's some example code:
+&gt; 
+&gt;     return shell_exec(&quot;echo $input | $markdown_script&quot;);
+</code></pre>
+
+<p>Any decent text editor should make email-style quoting easy. For
+example, with BBEdit, you can make a selection and choose Increase
+Quote Level from the Text menu.</p>
+
+<h3 id="list">Lists</h3>
+
+<p>Markdown supports ordered (numbered) and unordered (bulleted) lists.</p>
+
+<p>Unordered lists use asterisks, pluses, and hyphens -- interchangably
+-- as list markers:</p>
+
+<pre><code>*   Red
+*   Green
+*   Blue
+</code></pre>
+
+<p>is equivalent to:</p>
+
+<pre><code>+   Red
++   Green
++   Blue
+</code></pre>
+
+<p>and:</p>
+
+<pre><code>-   Red
+-   Green
+-   Blue
+</code></pre>
+
+<p>Ordered lists use numbers followed by periods:</p>
+
+<pre><code>1.  Bird
+2.  McHale
+3.  Parish
+</code></pre>
+
+<p>It's important to note that the actual numbers you use to mark the
+list have no effect on the HTML output Markdown produces. The HTML
+Markdown produces from the above list is:</p>
+
+<pre><code>&lt;ol&gt;
+&lt;li&gt;Bird&lt;/li&gt;
+&lt;li&gt;McHale&lt;/li&gt;
+&lt;li&gt;Parish&lt;/li&gt;
+&lt;/ol&gt;
+</code></pre>
+
+<p>If you instead wrote the list in Markdown like this:</p>
+
+<pre><code>1.  Bird
+1.  McHale
+1.  Parish
+</code></pre>
+
+<p>or even:</p>
+
+<pre><code>3. Bird
+1. McHale
+8. Parish
+</code></pre>
+
+<p>you'd get the exact same HTML output. The point is, if you want to,
+you can use ordinal numbers in your ordered Markdown lists, so that
+the numbers in your source match the numbers in your published HTML.
+But if you want to be lazy, you don't have to.</p>
+
+<p>If you do use lazy list numbering, however, you should still start the
+list with the number 1. At some point in the future, Markdown may support
+starting ordered lists at an arbitrary number.</p>
+
+<p>List markers typically start at the left margin, but may be indented by
+up to three spaces. List markers must be followed by one or more spaces
+or a tab.</p>
+
+<p>To make lists look nice, you can wrap items with hanging indents:</p>
+
+<pre><code>*   Lorem ipsum dolor sit amet, consectetuer adipiscing elit.
+    Aliquam hendrerit mi posuere lectus. Vestibulum enim wisi,
+    viverra nec, fringilla in, laoreet vitae, risus.
+*   Donec sit amet nisl. Aliquam semper ipsum sit amet velit.
+    Suspendisse id sem consectetuer libero luctus adipiscing.
+</code></pre>
+
+<p>But if you want to be lazy, you don't have to:</p>
+
+<pre><code>*   Lorem ipsum dolor sit amet, consectetuer adipiscing elit.
+Aliquam hendrerit mi posuere lectus. Vestibulum enim wisi,
+viverra nec, fringilla in, laoreet vitae, risus.
+*   Donec sit amet nisl. Aliquam semper ipsum sit amet velit.
+Suspendisse id sem consectetuer libero luctus adipiscing.
+</code></pre>
+
+<p>If list items are separated by blank lines, Markdown will wrap the
+items in <code>&lt;p&gt;</code> tags in the HTML output. For example, this input:</p>
+
+<pre><code>*   Bird
+*   Magic
+</code></pre>
+
+<p>will turn into:</p>
+
+<pre><code>&lt;ul&gt;
+&lt;li&gt;Bird&lt;/li&gt;
+&lt;li&gt;Magic&lt;/li&gt;
+&lt;/ul&gt;
+</code></pre>
+
+<p>But this:</p>
+
+<pre><code>*   Bird
+
+*   Magic
+</code></pre>
+
+<p>will turn into:</p>
+
+<pre><code>&lt;ul&gt;
+&lt;li&gt;&lt;p&gt;Bird&lt;/p&gt;&lt;/li&gt;
+&lt;li&gt;&lt;p&gt;Magic&lt;/p&gt;&lt;/li&gt;
+&lt;/ul&gt;
+</code></pre>
+
+<p>List items may consist of multiple paragraphs. Each subsequent
+paragraph in a list item must be intended by either 4 spaces
+or one tab:</p>
+
+<pre><code>1.  This is a list item with two paragraphs. Lorem ipsum dolor
+    sit amet, consectetuer adipiscing elit. Aliquam hendrerit
+    mi posuere lectus.
+
+    Vestibulum enim wisi, viverra nec, fringilla in, laoreet
+    vitae, risus. Donec sit amet nisl. Aliquam semper ipsum
+    sit amet velit.
+
+2.  Suspendisse id sem consectetuer libero luctus adipiscing.
+</code></pre>
+
+<p>It looks nice if you indent every line of the subsequent
+paragraphs, but here again, Markdown will allow you to be
+lazy:</p>
+
+<pre><code>*   This is a list item with two paragraphs.
+
+    This is the second paragraph in the list item. You're
+only required to indent the first line. Lorem ipsum dolor
+sit amet, consectetuer adipiscing elit.
+
+*   Another item in the same list.
+</code></pre>
+
+<p>To put a blockquote within a list item, the blockquote's <code>&gt;</code>
+delimiters need to be indented:</p>
+
+<pre><code>*   A list item with a blockquote:
+
+    &gt; This is a blockquote
+    &gt; inside a list item.
+</code></pre>
+
+<p>To put a code block within a list item, the code block needs
+to be indented <em>twice</em> -- 8 spaces or two tabs:</p>
+
+<pre><code>*   A list item with a code block:
+
+        &lt;code goes here&gt;
+</code></pre>
+
+<p>It's worth noting that it's possible to trigger an ordered list by
+accident, by writing something like this:</p>
+
+<pre><code>1986. What a great season.
+</code></pre>
+
+<p>In other words, a <em>number-period-space</em> sequence at the beginning of a
+line. To avoid this, you can backslash-escape the period:</p>
+
+<pre><code>1986\. What a great season.
+</code></pre>
+
+<h3 id="precode">Code Blocks</h3>
+
+<p>Pre-formatted code blocks are used for writing about programming or
+markup source code. Rather than forming normal paragraphs, the lines
+of a code block are interpreted literally. Markdown wraps a code block
+in both <code>&lt;pre&gt;</code> and <code>&lt;code&gt;</code> tags.</p>
+
+<p>To produce a code block in Markdown, simply indent every line of the
+block by at least 4 spaces or 1 tab. For example, given this input:</p>
+
+<pre><code>This is a normal paragraph:
+
+    This is a code block.
+</code></pre>
+
+<p>Markdown will generate:</p>
+
+<pre><code>&lt;p&gt;This is a normal paragraph:&lt;/p&gt;
+
+&lt;pre&gt;&lt;code&gt;This is a code block.
+&lt;/code&gt;&lt;/pre&gt;
+</code></pre>
+
+<p>One level of indentation -- 4 spaces or 1 tab -- is removed from each
+line of the code block. For example, this:</p>
+
+<pre><code>Here is an example of AppleScript:
+
+    tell application &quot;Foo&quot;
+        beep
+    end tell
+</code></pre>
+
+<p>will turn into:</p>
+
+<pre><code>&lt;p&gt;Here is an example of AppleScript:&lt;/p&gt;
+
+&lt;pre&gt;&lt;code&gt;tell application &quot;Foo&quot;
+    beep
+end tell
+&lt;/code&gt;&lt;/pre&gt;
+</code></pre>
+
+<p>A code block continues until it reaches a line that is not indented
+(or the end of the article).</p>
+
+<p>Within a code block, ampersands (<code>&amp;</code>) and angle brackets (<code>&lt;</code> and <code>&gt;</code>)
+are automatically converted into HTML entities. This makes it very
+easy to include example HTML source code using Markdown -- just paste
+it and indent it, and Markdown will handle the hassle of encoding the
+ampersands and angle brackets. For example, this:</p>
+
+<pre><code>    &lt;div class=&quot;footer&quot;&gt;
+        &amp;copy; 2004 Foo Corporation
+    &lt;/div&gt;
+</code></pre>
+
+<p>will turn into:</p>
+
+<pre><code>&lt;pre&gt;&lt;code&gt;&amp;lt;div class=&quot;footer&quot;&amp;gt;
+    &amp;amp;copy; 2004 Foo Corporation
+&amp;lt;/div&amp;gt;
+&lt;/code&gt;&lt;/pre&gt;
+</code></pre>
+
+<p>Regular Markdown syntax is not processed within code blocks. E.g.,
+asterisks are just literal asterisks within a code block. This means
+it's also easy to use Markdown to write about Markdown's own syntax.</p>
+
+<h3 id="hr">Horizontal Rules</h3>
+
+<p>You can produce a horizontal rule tag (<code>&lt;hr /&gt;</code>) by placing three or
+more hyphens, asterisks, or underscores on a line by themselves. If you
+wish, you may use spaces between the hyphens or asterisks. Each of the
+following lines will produce a horizontal rule:</p>
+
+<pre><code>* * *
+
+***
+
+*****
+
+- - -
+
+---------------------------------------
+
+_ _ _
+</code></pre>
+
+<hr>
+
+<h2 id="span">Span Elements</h2>
+
+<h3 id="link">Links</h3>
+
+<p>Markdown supports two style of links: <em>inline</em> and <em>reference</em>.</p>
+
+<p>In both styles, the link text is delimited by [square brackets].</p>
+
+<p>To create an inline link, use a set of regular parentheses immediately
+after the link text's closing square bracket. Inside the parentheses,
+put the URL where you want the link to point, along with an <em>optional</em>
+title for the link, surrounded in quotes. For example:</p>
+
+<pre><code>This is [an example](http://example.com/ &quot;Title&quot;) inline link.
+
+[This link](http://example.net/) has no title attribute.
+</code></pre>
+
+<p>Will produce:</p>
+
+<pre><code>&lt;p&gt;This is &lt;a href=&quot;http://example.com/&quot; title=&quot;Title&quot;&gt;
+an example&lt;/a&gt; inline link.&lt;/p&gt;
+
+&lt;p&gt;&lt;a href=&quot;http://example.net/&quot;&gt;This link&lt;/a&gt; has no
+title attribute.&lt;/p&gt;
+</code></pre>
+
+<p>If you're referring to a local resource on the same server, you can
+use relative paths:</p>
+
+<pre><code>See my [About](/about/) page for details.
+</code></pre>
+
+<p>Reference-style links use a second set of square brackets, inside
+which you place a label of your choosing to identify the link:</p>
+
+<pre><code>This is [an example][id] reference-style link.
+</code></pre>
+
+<p>You can optionally use a space to separate the sets of brackets:</p>
+
+<pre><code>This is [an example] [id] reference-style link.
+</code></pre>
+
+<p>Then, anywhere in the document, you define your link label like this,
+on a line by itself:</p>
+
+<pre><code>[id]: http://example.com/  &quot;Optional Title Here&quot;
+</code></pre>
+
+<p>That is:</p>
+
+<ul>
+<li>Square brackets containing the link identifier (optionally
+indented from the left margin using up to three spaces);</li>
+<li>followed by a colon;</li>
+<li>followed by one or more spaces (or tabs);</li>
+<li>followed by the URL for the link;</li>
+<li>optionally followed by a title attribute for the link, enclosed
+in double or single quotes.</li>
+</ul>
+
+<p>The link URL may, optionally, be surrounded by angle brackets:</p>
+
+<pre><code>[id]: &lt;http://example.com/&gt;  &quot;Optional Title Here&quot;
+</code></pre>
+
+<p>You can put the title attribute on the next line and use extra spaces
+or tabs for padding, which tends to look better with longer URLs:</p>
+
+<pre><code>[id]: http://example.com/longish/path/to/resource/here
+    &quot;Optional Title Here&quot;
+</code></pre>
+
+<p>Link definitions are only used for creating links during Markdown
+processing, and are stripped from your document in the HTML output.</p>
+
+<p>Link definition names may constist of letters, numbers, spaces, and punctuation -- but they are <em>not</em> case sensitive. E.g. these two links:</p>
+
+<pre><code>[link text][a]
+[link text][A]
+</code></pre>
+
+<p>are equivalent.</p>
+
+<p>The <em>implicit link name</em> shortcut allows you to omit the name of the
+link, in which case the link text itself is used as the name.
+Just use an empty set of square brackets -- e.g., to link the word
+&quot;Google&quot; to the google.com web site, you could simply write:</p>
+
+<pre><code>[Google][]
+</code></pre>
+
+<p>And then define the link:</p>
+
+<pre><code>[Google]: http://google.com/
+</code></pre>
+
+<p>Because link names may contain spaces, this shortcut even works for
+multiple words in the link text:</p>
+
+<pre><code>Visit [Daring Fireball][] for more information.
+</code></pre>
+
+<p>And then define the link:</p>
+
+<pre><code>[Daring Fireball]: http://daringfireball.net/
+</code></pre>
+
+<p>Link definitions can be placed anywhere in your Markdown document. I
+tend to put them immediately after each paragraph in which they're
+used, but if you want, you can put them all at the end of your
+document, sort of like footnotes.</p>
+
+<p>Here's an example of reference links in action:</p>
+
+<pre><code>I get 10 times more traffic from [Google] [1] than from
+[Yahoo] [2] or [MSN] [3].
+
+  [1]: http://google.com/        &quot;Google&quot;
+  [2]: http://search.yahoo.com/  &quot;Yahoo Search&quot;
+  [3]: http://search.msn.com/    &quot;MSN Search&quot;
+</code></pre>
+
+<p>Using the implicit link name shortcut, you could instead write:</p>
+
+<pre><code>I get 10 times more traffic from [Google][] than from
+[Yahoo][] or [MSN][].
+
+  [google]: http://google.com/        &quot;Google&quot;
+  [yahoo]:  http://search.yahoo.com/  &quot;Yahoo Search&quot;
+  [msn]:    http://search.msn.com/    &quot;MSN Search&quot;
+</code></pre>
+
+<p>Both of the above examples will produce the following HTML output:</p>
+
+<pre><code>&lt;p&gt;I get 10 times more traffic from &lt;a href=&quot;http://google.com/&quot;
+title=&quot;Google&quot;&gt;Google&lt;/a&gt; than from
+&lt;a href=&quot;http://search.yahoo.com/&quot; title=&quot;Yahoo Search&quot;&gt;Yahoo&lt;/a&gt;
+or &lt;a href=&quot;http://search.msn.com/&quot; title=&quot;MSN Search&quot;&gt;MSN&lt;/a&gt;.&lt;/p&gt;
+</code></pre>
+
+<p>For comparison, here is the same paragraph written using
+Markdown's inline link style:</p>
+
+<pre><code>I get 10 times more traffic from [Google](http://google.com/ &quot;Google&quot;)
+than from [Yahoo](http://search.yahoo.com/ &quot;Yahoo Search&quot;) or
+[MSN](http://search.msn.com/ &quot;MSN Search&quot;).
+</code></pre>
+
+<p>The point of reference-style links is not that they're easier to
+write. The point is that with reference-style links, your document
+source is vastly more readable. Compare the above examples: using
+reference-style links, the paragraph itself is only 81 characters
+long; with inline-style links, it's 176 characters; and as raw HTML,
+it's 234 characters. In the raw HTML, there's more markup than there
+is text.</p>
+
+<p>With Markdown's reference-style links, a source document much more
+closely resembles the final output, as rendered in a browser. By
+allowing you to move the markup-related metadata out of the paragraph,
+you can add links without interrupting the narrative flow of your
+prose.</p>
+
+<h3 id="em">Emphasis</h3>
+
+<p>Markdown treats asterisks (<code>*</code>) and underscores (<code>_</code>) as indicators of
+emphasis. Text wrapped with one <code>*</code> or <code>_</code> will be wrapped with an
+HTML <code>&lt;em&gt;</code> tag; double <code>*</code>'s or <code>_</code>'s will be wrapped with an HTML
+<code>&lt;strong&gt;</code> tag. E.g., this input:</p>
+
+<pre><code>*single asterisks*
+
+_single underscores_
+
+**double asterisks**
+
+__double underscores__
+</code></pre>
+
+<p>will produce:</p>
+
+<pre><code>&lt;em&gt;single asterisks&lt;/em&gt;
+
+&lt;em&gt;single underscores&lt;/em&gt;
+
+&lt;strong&gt;double asterisks&lt;/strong&gt;
+
+&lt;strong&gt;double underscores&lt;/strong&gt;
+</code></pre>
+
+<p>You can use whichever style you prefer; the lone restriction is that
+the same character must be used to open and close an emphasis span.</p>
+
+<p>Emphasis can be used in the middle of a word:</p>
+
+<pre><code>un*fucking*believable
+</code></pre>
+
+<p>But if you surround an <code>*</code> or <code>_</code> with spaces, it'll be treated as a
+literal asterisk or underscore.</p>
+
+<p>To produce a literal asterisk or underscore at a position where it
+would otherwise be used as an emphasis delimiter, you can backslash
+escape it:</p>
+
+<pre><code>\*this text is surrounded by literal asterisks\*
+</code></pre>
+
+<h3 id="code">Code</h3>
+
+<p>To indicate a span of code, wrap it with backtick quotes (<code>`</code>).
+Unlike a pre-formatted code block, a code span indicates code within a
+normal paragraph. For example:</p>
+
+<pre><code>Use the `printf()` function.
+</code></pre>
+
+<p>will produce:</p>
+
+<pre><code>&lt;p&gt;Use the &lt;code&gt;printf()&lt;/code&gt; function.&lt;/p&gt;
+</code></pre>
+
+<p>To include a literal backtick character within a code span, you can use
+multiple backticks as the opening and closing delimiters:</p>
+
+<pre><code>``There is a literal backtick (`) here.``
+</code></pre>
+
+<p>which will produce this:</p>
+
+<pre><code>&lt;p&gt;&lt;code&gt;There is a literal backtick (`) here.&lt;/code&gt;&lt;/p&gt;
+</code></pre>
+
+<p>The backtick delimiters surrounding a code span may include spaces --
+one after the opening, one before the closing. This allows you to place
+literal backtick characters at the beginning or end of a code span:</p>
+
+<pre><code>A single backtick in a code span: `` ` ``
+
+A backtick-delimited string in a code span: `` `foo` ``
+</code></pre>
+
+<p>will produce:</p>
+
+<pre><code>&lt;p&gt;A single backtick in a code span: &lt;code&gt;`&lt;/code&gt;&lt;/p&gt;
+
+&lt;p&gt;A backtick-delimited string in a code span: &lt;code&gt;`foo`&lt;/code&gt;&lt;/p&gt;
+</code></pre>
+
+<p>With a code span, ampersands and angle brackets are encoded as HTML
+entities automatically, which makes it easy to include example HTML
+tags. Markdown will turn this:</p>
+
+<pre><code>Please don't use any `&lt;blink&gt;` tags.
+</code></pre>
+
+<p>into:</p>
+
+<pre><code>&lt;p&gt;Please don't use any &lt;code&gt;&amp;lt;blink&amp;gt;&lt;/code&gt; tags.&lt;/p&gt;
+</code></pre>
+
+<p>You can write this:</p>
+
+<pre><code>`&amp;#8212;` is the decimal-encoded equivalent of `&amp;mdash;`.
+</code></pre>
+
+<p>to produce:</p>
+
+<pre><code>&lt;p&gt;&lt;code&gt;&amp;amp;#8212;&lt;/code&gt; is the decimal-encoded
+equivalent of &lt;code&gt;&amp;amp;mdash;&lt;/code&gt;.&lt;/p&gt;
+</code></pre>
+
+<h3 id="img">Images</h3>
+
+<p>Admittedly, it's fairly difficult to devise a &quot;natural&quot; syntax for
+placing images into a plain text document format.</p>
+
+<p>Markdown uses an image syntax that is intended to resemble the syntax
+for links, allowing for two styles: <em>inline</em> and <em>reference</em>.</p>
+
+<p>Inline image syntax looks like this:</p>
+
+<pre><code>![Alt text](/path/to/img.jpg)
+
+![Alt text](/path/to/img.jpg &quot;Optional title&quot;)
+</code></pre>
+
+<p>That is:</p>
+
+<ul>
+<li>An exclamation mark: <code>!</code>;</li>
+<li>followed by a set of square brackets, containing the <code>alt</code>
+attribute text for the image;</li>
+<li>followed by a set of parentheses, containing the URL or path to
+the image, and an optional <code>title</code> attribute enclosed in double
+or single quotes.</li>
+</ul>
+
+<p>Reference-style image syntax looks like this:</p>
+
+<pre><code>![Alt text][id]
+</code></pre>
+
+<p>Where &quot;id&quot; is the name of a defined image reference. Image references
+are defined using syntax identical to link references:</p>
+
+<pre><code>[id]: url/to/image  &quot;Optional title attribute&quot;
+</code></pre>
+
+<p>As of this writing, Markdown has no syntax for specifying the
+dimensions of an image; if this is important to you, you can simply
+use regular HTML <code>&lt;img&gt;</code> tags.</p>
+
+<hr>
+
+<h2 id="misc">Miscellaneous</h2>
+
+<h3 id="autolink">Automatic Links</h3>
+
+<p>Markdown supports a shortcut style for creating &quot;automatic&quot; links for URLs and email addresses: simply surround the URL or email address with angle brackets. What this means is that if you want to show the actual text of a URL or email address, and also have it be a clickable link, you can do this:</p>
+
+<pre><code>&lt;http://example.com/&gt;
+</code></pre>
+
+<p>Markdown will turn this into:</p>
+
+<pre><code>&lt;a href=&quot;http://example.com/&quot;&gt;http://example.com/&lt;/a&gt;
+</code></pre>
+
+<p>Automatic links for email addresses work similarly, except that
+Markdown will also perform a bit of randomized decimal and hex
+entity-encoding to help obscure your address from address-harvesting
+spambots. For example, Markdown will turn this:</p>
+
+<pre><code>&lt;address@example.com&gt;
+</code></pre>
+
+<p>into something like this:</p>
+
+<pre><code>&lt;a href=&quot;&amp;#x6D;&amp;#x61;i&amp;#x6C;&amp;#x74;&amp;#x6F;:&amp;#x61;&amp;#x64;&amp;#x64;&amp;#x72;&amp;#x65;
+&amp;#115;&amp;#115;&amp;#64;&amp;#101;&amp;#120;&amp;#x61;&amp;#109;&amp;#x70;&amp;#x6C;e&amp;#x2E;&amp;#99;&amp;#111;
+&amp;#109;&quot;&gt;&amp;#x61;&amp;#x64;&amp;#x64;&amp;#x72;&amp;#x65;&amp;#115;&amp;#115;&amp;#64;&amp;#101;&amp;#120;&amp;#x61;
+&amp;#109;&amp;#x70;&amp;#x6C;e&amp;#x2E;&amp;#99;&amp;#111;&amp;#109;&lt;/a&gt;
+</code></pre>
+
+<p>which will render in a browser as a clickable link to &quot;address@example.com&quot;.</p>
+
+<p>(This sort of entity-encoding trick will indeed fool many, if not
+most, address-harvesting bots, but it definitely won't fool all of
+them. It's better than nothing, but an address published in this way
+will probably eventually start receiving spam.)</p>
+
+<h3 id="backslash">Backslash Escapes</h3>
+
+<p>Markdown allows you to use backslash escapes to generate literal
+characters which would otherwise have special meaning in Markdown's
+formatting syntax. For example, if you wanted to surround a word with
+literal asterisks (instead of an HTML <code>&lt;em&gt;</code> tag), you can backslashes
+before the asterisks, like this:</p>
+
+<pre><code>\*literal asterisks\*
+</code></pre>
+
+<p>Markdown provides backslash escapes for the following characters:</p>
+
+<pre><code>\   backslash
+`   backtick
+*   asterisk
+_   underscore
+{}  curly braces
+[]  square brackets
+()  parentheses
+#   hash mark
++   plus sign
+-   minus sign (hyphen)
+.   dot
+!   exclamation mark
+</code></pre>

+<h2 id="overview">Overview</h2>
+
+<h3 id="philosophy">Philosophy</h3>
+
+Markdown is intended to be as easy-to-read and easy-to-write as is feasible.
+
+Readability, however, is emphasized above all else. A Markdown-formatted
+document should be publishable as-is, as plain text, without looking
+like it's been marked up with tags or formatting instructions. While
+Markdown's syntax has been influenced by several existing text-to-HTML
+filters -- including [Setext] [1], [atx] [2], [Textile] [3], [reStructuredText] [4],
+[Grutatext] [5], and [EtText] [6] -- the single biggest source of
+inspiration for Markdown's syntax is the format of plain text email.
+
+  [1]: http://docutils.sourceforge.net/mirror/setext.html
+  [2]: http://www.aaronsw.com/2002/atx/
+  [3]: http://textism.com/tools/textile/
+  [4]: http://docutils.sourceforge.net/rst.html
+  [5]: http://www.triptico.com/software/grutatxt.html
+  [6]: http://ettext.taint.org/doc/
+
+To this end, Markdown's syntax is comprised entirely of punctuation
+characters, which punctuation characters have been carefully chosen so
+as to look like what they mean. E.g., asterisks around a word actually
+look like \*emphasis\*. Markdown lists look like, well, lists. Even
+blockquotes look like quoted passages of text, assuming you've ever
+used email.
+
+
+
+<h3 id="html">Inline HTML</h3>
+
+Markdown's syntax is intended for one purpose: to be used as a
+format for *writing* for the web.
+
+Markdown is not a replacement for HTML, or even close to it. Its
+syntax is very small, corresponding only to a very small subset of
+HTML tags. The idea is *not* to create a syntax that makes it easier
+to insert HTML tags. In my opinion, HTML tags are already easy to
+insert. The idea for Markdown is to make it easy to read, write, and
+edit prose. HTML is a *publishing* format; Markdown is a *writing*
+format. Thus, Markdown's formatting syntax only addresses issues that
+can be conveyed in plain text.
+
+For any markup that is not covered by Markdown's syntax, you simply
+use HTML itself. There's no need to preface it or delimit it to
+indicate that you're switching from Markdown to HTML; you just use
+the tags.
+
+The only restrictions are that block-level HTML elements -- e.g. `<div>`,
+`<table>`, `<pre>`, `<p>`, etc. -- must be separated from surrounding
+content by blank lines, and the start and end tags of the block should
+not be indented with tabs or spaces. Markdown is smart enough not
+to add extra (unwanted) `<p>` tags around HTML block-level tags.
+
+For example, to add an HTML table to a Markdown article:
+
+    This is a regular paragraph.
+
+    <table>
+        <tr>
+            <td>Foo</td>
+        </tr>
+    </table>
+
+    This is another regular paragraph.
+
+Note that Markdown formatting syntax is not processed within block-level
+HTML tags. E.g., you can't use Markdown-style `*emphasis*` inside an
+HTML block.
+
+Span-level HTML tags -- e.g. `<span>`, `<cite>`, or `<del>` -- can be
+used anywhere in a Markdown paragraph, list item, or header. If you
+want, you can even use HTML tags instead of Markdown formatting; e.g. if
+you'd prefer to use HTML `<a>` or `<img>` tags instead of Markdown's
+link or image syntax, go right ahead.
+
+Unlike block-level HTML tags, Markdown syntax *is* processed within
+span-level tags.
+
+
+<h3 id="autoescape">Automatic Escaping for Special Characters</h3>
+
+In HTML, there are two characters that demand special treatment: `<`
+and `&`. Left angle brackets are used to start tags; ampersands are
+used to denote HTML entities. If you want to use them as literal
+characters, you must escape them as entities, e.g. `&lt;`, and
+`&amp;`.
+
+Ampersands in particular are bedeviling for web writers. If you want to
+write about 'AT&T', you need to write '`AT&amp;T`'. You even need to
+escape ampersands within URLs. Thus, if you want to link to:
+
+    http://images.google.com/images?num=30&q=larry+bird
+
+you need to encode the URL as:
+
+    http://images.google.com/images?num=30&amp;q=larry+bird
+
+in your anchor tag `href` attribute. Needless to say, this is easy to
+forget, and is probably the single most common source of HTML validation
+errors in otherwise well-marked-up web sites.
+
+Markdown allows you to use these characters naturally, taking care of
+all the necessary escaping for you. If you use an ampersand as part of
+an HTML entity, it remains unchanged; otherwise it will be translated
+into `&amp;`.
+
+So, if you want to include a copyright symbol in your article, you can write:
+
+    &copy;
+
+and Markdown will leave it alone. But if you write:
+
+    AT&T
+
+Markdown will translate it to:
+
+    AT&amp;T
+
+Similarly, because Markdown supports [inline HTML](#html), if you use
+angle brackets as delimiters for HTML tags, Markdown will treat them as
+such. But if you write:
+
+    4 < 5
+
+Markdown will translate it to:
+
+    4 &lt; 5
+
+However, inside Markdown code spans and blocks, angle brackets and
+ampersands are *always* encoded automatically. This makes it easy to use
+Markdown to write about HTML code. (As opposed to raw HTML, which is a
+terrible format for writing about HTML syntax, because every single `<`
+and `&` in your example code needs to be escaped.)
+
+
+* * *
+
+
+<h2 id="block">Block Elements</h2>
+
+
+<h3 id="p">Paragraphs and Line Breaks</h3>
+
+A paragraph is simply one or more consecutive lines of text, separated
+by one or more blank lines. (A blank line is any line that looks like a
+blank line -- a line containing nothing but spaces or tabs is considered
+blank.) Normal paragraphs should not be intended with spaces or tabs.
+
+The implication of the "one or more consecutive lines of text" rule is
+that Markdown supports "hard-wrapped" text paragraphs. This differs
+significantly from most other text-to-HTML formatters (including Movable
+Type's "Convert Line Breaks" option) which translate every line break
+character in a paragraph into a `<br />` tag.
+
+When you *do* want to insert a `<br />` break tag using Markdown, you
+end a line with two or more spaces, then type return.
+
+Yes, this takes a tad more effort to create a `<br />`, but a simplistic
+"every line break is a `<br />`" rule wouldn't work for Markdown.
+Markdown's email-style [blockquoting][bq] and multi-paragraph [list items][l]
+work best -- and look better -- when you format them with hard breaks.
+
+  [bq]: #blockquote
+  [l]:  #list
+
+
+
+<h3 id="header">Headers</h3>
+
+Markdown supports two styles of headers, [Setext] [1] and [atx] [2].
+
+Setext-style headers are "underlined" using equal signs (for first-level
+headers) and dashes (for second-level headers). For example:
+
+    This is an H1
+    =============
+
+    This is an H2
+    -------------
+
+Any number of underlining `=`'s or `-`'s will work.
+
+Atx-style headers use 1-6 hash characters at the start of the line,
+corresponding to header levels 1-6. For example:
+
+    # This is an H1
+
+    ## This is an H2
+
+    ###### This is an H6
+
+Optionally, you may "close" atx-style headers. This is purely
+cosmetic -- you can use this if you think it looks better. The
+closing hashes don't even need to match the number of hashes
+used to open the header. (The number of opening hashes
+determines the header level.) :
+
+    # This is an H1 #
+
+    ## This is an H2 ##
+
+    ### This is an H3 ######
+
+
+<h3 id="blockquote">Blockquotes</h3>
+
+Markdown uses email-style `>` characters for blockquoting. If you're
+familiar with quoting passages of text in an email message, then you
+know how to create a blockquote in Markdown. It looks best if you hard
+wrap the text and put a `>` before every line:
+
+    > This is a blockquote with two paragraphs. Lorem ipsum dolor sit amet,
+    > consectetuer adipiscing elit. Aliquam hendrerit mi posuere lectus.
+    > Vestibulum enim wisi, viverra nec, fringilla in, laoreet vitae, risus.
+    > 
+    > Donec sit amet nisl. Aliquam semper ipsum sit amet velit. Suspendisse
+    > id sem consectetuer libero luctus adipiscing.
+
+Markdown allows you to be lazy and only put the `>` before the first
+line of a hard-wrapped paragraph:
+
+    > This is a blockquote with two paragraphs. Lorem ipsum dolor sit amet,
+    consectetuer adipiscing elit. Aliquam hendrerit mi posuere lectus.
+    Vestibulum enim wisi, viverra nec, fringilla in, laoreet vitae, risus.
+
+    > Donec sit amet nisl. Aliquam semper ipsum sit amet velit. Suspendisse
+    id sem consectetuer libero luctus adipiscing.
+
+Blockquotes can be nested (i.e. a blockquote-in-a-blockquote) by
+adding additional levels of `>`:
+
+    > This is the first level of quoting.
+    >
+    > > This is nested blockquote.
+    >
+    > Back to the first level.
+
+Blockquotes can contain other Markdown elements, including headers, lists,
+and code blocks:
+
+	> ## This is a header.
+	> 
+	> 1.   This is the first list item.
+	> 2.   This is the second list item.
+	> 
+	> Here's some example code:
+	> 
+	>     return shell_exec("echo $input | $markdown_script");
+
+Any decent text editor should make email-style quoting easy. For
+example, with BBEdit, you can make a selection and choose Increase
+Quote Level from the Text menu.
+
+
+<h3 id="list">Lists</h3>
+
+Markdown supports ordered (numbered) and unordered (bulleted) lists.
+
+Unordered lists use asterisks, pluses, and hyphens -- interchangably
+-- as list markers:
+
+    *   Red
+    *   Green
+    *   Blue
+
+is equivalent to:
+
+    +   Red
+    +   Green
+    +   Blue
+
+and:
+
+    -   Red
+    -   Green
+    -   Blue
+
+Ordered lists use numbers followed by periods:
+
+    1.  Bird
+    2.  McHale
+    3.  Parish
+
+It's important to note that the actual numbers you use to mark the
+list have no effect on the HTML output Markdown produces. The HTML
+Markdown produces from the above list is:
+
+    <ol>
+    <li>Bird</li>
+    <li>McHale</li>
+    <li>Parish</li>
+    </ol>
+
+If you instead wrote the list in Markdown like this:
+
+    1.  Bird
+    1.  McHale
+    1.  Parish
+
+or even:
+
+    3. Bird
+    1. McHale
+    8. Parish
+
+you'd get the exact same HTML output. The point is, if you want to,
+you can use ordinal numbers in your ordered Markdown lists, so that
+the numbers in your source match the numbers in your published HTML.
+But if you want to be lazy, you don't have to.
+
+If you do use lazy list numbering, however, you should still start the
+list with the number 1. At some point in the future, Markdown may support
+starting ordered lists at an arbitrary number.
+
+List markers typically start at the left margin, but may be indented by
+up to three spaces. List markers must be followed by one or more spaces
+or a tab.
+
+To make lists look nice, you can wrap items with hanging indents:
+
+    *   Lorem ipsum dolor sit amet, consectetuer adipiscing elit.
+        Aliquam hendrerit mi posuere lectus. Vestibulum enim wisi,
+        viverra nec, fringilla in, laoreet vitae, risus.
+    *   Donec sit amet nisl. Aliquam semper ipsum sit amet velit.
+        Suspendisse id sem consectetuer libero luctus adipiscing.
+
+But if you want to be lazy, you don't have to:
+
+    *   Lorem ipsum dolor sit amet, consectetuer adipiscing elit.
+    Aliquam hendrerit mi posuere lectus. Vestibulum enim wisi,
+    viverra nec, fringilla in, laoreet vitae, risus.
+    *   Donec sit amet nisl. Aliquam semper ipsum sit amet velit.
+    Suspendisse id sem consectetuer libero luctus adipiscing.
+
+If list items are separated by blank lines, Markdown will wrap the
+items in `<p>` tags in the HTML output. For example, this input:
+
+    *   Bird
+    *   Magic
+
+will turn into:
+
+    <ul>
+    <li>Bird</li>
+    <li>Magic</li>
+    </ul>
+
+But this:
+
+    *   Bird
+
+    *   Magic
+
+will turn into:
+
+    <ul>
+    <li><p>Bird</p></li>
+    <li><p>Magic</p></li>
+    </ul>
+
+List items may consist of multiple paragraphs. Each subsequent
+paragraph in a list item must be intended by either 4 spaces
+or one tab:
+
+    1.  This is a list item with two paragraphs. Lorem ipsum dolor
+        sit amet, consectetuer adipiscing elit. Aliquam hendrerit
+        mi posuere lectus.
+
+        Vestibulum enim wisi, viverra nec, fringilla in, laoreet
+        vitae, risus. Donec sit amet nisl. Aliquam semper ipsum
+        sit amet velit.
+
+    2.  Suspendisse id sem consectetuer libero luctus adipiscing.
+
+It looks nice if you indent every line of the subsequent
+paragraphs, but here again, Markdown will allow you to be
+lazy:
+
+    *   This is a list item with two paragraphs.
+
+        This is the second paragraph in the list item. You're
+    only required to indent the first line. Lorem ipsum dolor
+    sit amet, consectetuer adipiscing elit.
+
+    *   Another item in the same list.
+
+To put a blockquote within a list item, the blockquote's `>`
+delimiters need to be indented:
+
+    *   A list item with a blockquote:
+
+        > This is a blockquote
+        > inside a list item.
+
+To put a code block within a list item, the code block needs
+to be indented *twice* -- 8 spaces or two tabs:
+
+    *   A list item with a code block:
+
+            <code goes here>
+
+
+It's worth noting that it's possible to trigger an ordered list by
+accident, by writing something like this:
+
+    1986. What a great season.
+
+In other words, a *number-period-space* sequence at the beginning of a
+line. To avoid this, you can backslash-escape the period:
+
+    1986\. What a great season.
+
+
+
+<h3 id="precode">Code Blocks</h3>
+
+Pre-formatted code blocks are used for writing about programming or
+markup source code. Rather than forming normal paragraphs, the lines
+of a code block are interpreted literally. Markdown wraps a code block
+in both `<pre>` and `<code>` tags.
+
+To produce a code block in Markdown, simply indent every line of the
+block by at least 4 spaces or 1 tab. For example, given this input:
+
+    This is a normal paragraph:
+
+        This is a code block.
+
+Markdown will generate:
+
+    <p>This is a normal paragraph:</p>
+
+    <pre><code>This is a code block.
+    </code></pre>
+
+One level of indentation -- 4 spaces or 1 tab -- is removed from each
+line of the code block. For example, this:
+
+    Here is an example of AppleScript:
+
+        tell application "Foo"
+            beep
+        end tell
+
+will turn into:
+
+    <p>Here is an example of AppleScript:</p>
+
+    <pre><code>tell application "Foo"
+        beep
+    end tell
+    </code></pre>
+
+A code block continues until it reaches a line that is not indented
+(or the end of the article).
+
+Within a code block, ampersands (`&`) and angle brackets (`<` and `>`)
+are automatically converted into HTML entities. This makes it very
+easy to include example HTML source code using Markdown -- just paste
+it and indent it, and Markdown will handle the hassle of encoding the
+ampersands and angle brackets. For example, this:
+
+        <div class="footer">
+            &copy; 2004 Foo Corporation
+        </div>
+
+will turn into:
+
+    <pre><code>&lt;div class="footer"&gt;
+        &amp;copy; 2004 Foo Corporation
+    &lt;/div&gt;
+    </code></pre>
+
+Regular Markdown syntax is not processed within code blocks. E.g.,
+asterisks are just literal asterisks within a code block. This means
+it's also easy to use Markdown to write about Markdown's own syntax.
+
+
+
+<h3 id="hr">Horizontal Rules</h3>
+
+You can produce a horizontal rule tag (`<hr />`) by placing three or
+more hyphens, asterisks, or underscores on a line by themselves. If you
+wish, you may use spaces between the hyphens or asterisks. Each of the
+following lines will produce a horizontal rule:
+
+    * * *
+
+    ***
+
+    *****
+	
+    - - -
+
+    ---------------------------------------
+
+	_ _ _
+
+
+* * *
+
+<h2 id="span">Span Elements</h2>
+
+<h3 id="link">Links</h3>
+
+Markdown supports two style of links: *inline* and *reference*.
+
+In both styles, the link text is delimited by [square brackets].
+
+To create an inline link, use a set of regular parentheses immediately
+after the link text's closing square bracket. Inside the parentheses,
+put the URL where you want the link to point, along with an *optional*
+title for the link, surrounded in quotes. For example:
+
+    This is [an example](http://example.com/ "Title") inline link.
+
+    [This link](http://example.net/) has no title attribute.
+
+Will produce:
+
+    <p>This is <a href="http://example.com/" title="Title">
+    an example</a> inline link.</p>
+
+    <p><a href="http://example.net/">This link</a> has no
+    title attribute.</p>
+
+If you're referring to a local resource on the same server, you can
+use relative paths:
+
+    See my [About](/about/) page for details.
+
+Reference-style links use a second set of square brackets, inside
+which you place a label of your choosing to identify the link:
+
+    This is [an example][id] reference-style link.
+
+You can optionally use a space to separate the sets of brackets:
+
+    This is [an example] [id] reference-style link.
+
+Then, anywhere in the document, you define your link label like this,
+on a line by itself:
+
+    [id]: http://example.com/  "Optional Title Here"
+
+That is:
+
+*   Square brackets containing the link identifier (optionally
+    indented from the left margin using up to three spaces);
+*   followed by a colon;
+*   followed by one or more spaces (or tabs);
+*   followed by the URL for the link;
+*   optionally followed by a title attribute for the link, enclosed
+    in double or single quotes.
+
+The link URL may, optionally, be surrounded by angle brackets:
+
+    [id]: <http://example.com/>  "Optional Title Here"
+
+You can put the title attribute on the next line and use extra spaces
+or tabs for padding, which tends to look better with longer URLs:
+
+    [id]: http://example.com/longish/path/to/resource/here
+        "Optional Title Here"
+
+Link definitions are only used for creating links during Markdown
+processing, and are stripped from your document in the HTML output.
+
+Link definition names may constist of letters, numbers, spaces, and punctuation -- but they are *not* case sensitive. E.g. these two links:
+
+	[link text][a]
+	[link text][A]
+
+are equivalent.
+
+The *implicit link name* shortcut allows you to omit the name of the
+link, in which case the link text itself is used as the name.
+Just use an empty set of square brackets -- e.g., to link the word
+"Google" to the google.com web site, you could simply write:
+
+	[Google][]
+
+And then define the link:
+
+	[Google]: http://google.com/
+
+Because link names may contain spaces, this shortcut even works for
+multiple words in the link text:
+
+	Visit [Daring Fireball][] for more information.
+
+And then define the link:
+	
+	[Daring Fireball]: http://daringfireball.net/
+
+Link definitions can be placed anywhere in your Markdown document. I
+tend to put them immediately after each paragraph in which they're
+used, but if you want, you can put them all at the end of your
+document, sort of like footnotes.
+
+Here's an example of reference links in action:
+
+    I get 10 times more traffic from [Google] [1] than from
+    [Yahoo] [2] or [MSN] [3].
+
+      [1]: http://google.com/        "Google"
+      [2]: http://search.yahoo.com/  "Yahoo Search"
+      [3]: http://search.msn.com/    "MSN Search"
+
+Using the implicit link name shortcut, you could instead write:
+
+    I get 10 times more traffic from [Google][] than from
+    [Yahoo][] or [MSN][].
+
+      [google]: http://google.com/        "Google"
+      [yahoo]:  http://search.yahoo.com/  "Yahoo Search"
+      [msn]:    http://search.msn.com/    "MSN Search"
+
+Both of the above examples will produce the following HTML output:
+
+    <p>I get 10 times more traffic from <a href="http://google.com/"
+    title="Google">Google</a> than from
+    <a href="http://search.yahoo.com/" title="Yahoo Search">Yahoo</a>
+    or <a href="http://search.msn.com/" title="MSN Search">MSN</a>.</p>
+
+For comparison, here is the same paragraph written using
+Markdown's inline link style:
+
+    I get 10 times more traffic from [Google](http://google.com/ "Google")
+    than from [Yahoo](http://search.yahoo.com/ "Yahoo Search") or
+    [MSN](http://search.msn.com/ "MSN Search").
+
+The point of reference-style links is not that they're easier to
+write. The point is that with reference-style links, your document
+source is vastly more readable. Compare the above examples: using
+reference-style links, the paragraph itself is only 81 characters
+long; with inline-style links, it's 176 characters; and as raw HTML,
+it's 234 characters. In the raw HTML, there's more markup than there
+is text.
+
+With Markdown's reference-style links, a source document much more
+closely resembles the final output, as rendered in a browser. By
+allowing you to move the markup-related metadata out of the paragraph,
+you can add links without interrupting the narrative flow of your
+prose.
+
+
+<h3 id="em">Emphasis</h3>
+
+Markdown treats asterisks (`*`) and underscores (`_`) as indicators of
+emphasis. Text wrapped with one `*` or `_` will be wrapped with an
+HTML `<em>` tag; double `*`'s or `_`'s will be wrapped with an HTML
+`<strong>` tag. E.g., this input:
+
+    *single asterisks*
+
+    _single underscores_
+
+    **double asterisks**
+
+    __double underscores__
+
+will produce:
+
+    <em>single asterisks</em>
+
+    <em>single underscores</em>
+
+    <strong>double asterisks</strong>
+
+    <strong>double underscores</strong>
+
+You can use whichever style you prefer; the lone restriction is that
+the same character must be used to open and close an emphasis span.
+
+Emphasis can be used in the middle of a word:
+
+    un*fucking*believable
+
+But if you surround an `*` or `_` with spaces, it'll be treated as a
+literal asterisk or underscore.
+
+To produce a literal asterisk or underscore at a position where it
+would otherwise be used as an emphasis delimiter, you can backslash
+escape it:
+
+    \*this text is surrounded by literal asterisks\*
+
+
+
+<h3 id="code">Code</h3>
+
+To indicate a span of code, wrap it with backtick quotes (`` ` ``).
+Unlike a pre-formatted code block, a code span indicates code within a
+normal paragraph. For example:
+
+    Use the `printf()` function.
+
+will produce:
+
+    <p>Use the <code>printf()</code> function.</p>
+
+To include a literal backtick character within a code span, you can use
+multiple backticks as the opening and closing delimiters:
+
+    ``There is a literal backtick (`) here.``
+
+which will produce this:
+
+    <p><code>There is a literal backtick (`) here.</code></p>
+
+The backtick delimiters surrounding a code span may include spaces --
+one after the opening, one before the closing. This allows you to place
+literal backtick characters at the beginning or end of a code span:
+
+	A single backtick in a code span: `` ` ``
+	
+	A backtick-delimited string in a code span: `` `foo` ``
+
+will produce:
+
+	<p>A single backtick in a code span: <code>`</code></p>
+	
+	<p>A backtick-delimited string in a code span: <code>`foo`</code></p>
+
+With a code span, ampersands and angle brackets are encoded as HTML
+entities automatically, which makes it easy to include example HTML
+tags. Markdown will turn this:
+
+    Please don't use any `<blink>` tags.
+
+into:
+
+    <p>Please don't use any <code>&lt;blink&gt;</code> tags.</p>
+
+You can write this:
+
+    `&#8212;` is the decimal-encoded equivalent of `&mdash;`.
+
+to produce:
+
+    <p><code>&amp;#8212;</code> is the decimal-encoded
+    equivalent of <code>&amp;mdash;</code>.</p>
+
+
+
+<h3 id="img">Images</h3>
+
+Admittedly, it's fairly difficult to devise a "natural" syntax for
+placing images into a plain text document format.
+
+Markdown uses an image syntax that is intended to resemble the syntax
+for links, allowing for two styles: *inline* and *reference*.
+
+Inline image syntax looks like this:
+
+    ![Alt text](/path/to/img.jpg)
+
+    ![Alt text](/path/to/img.jpg "Optional title")
+
+That is:
+
+*   An exclamation mark: `!`;
+*   followed by a set of square brackets, containing the `alt`
+    attribute text for the image;
+*   followed by a set of parentheses, containing the URL or path to
+    the image, and an optional `title` attribute enclosed in double
+    or single quotes.
+
+Reference-style image syntax looks like this:
+
+    ![Alt text][id]
+
+Where "id" is the name of a defined image reference. Image references
+are defined using syntax identical to link references:
+
+    [id]: url/to/image  "Optional title attribute"
+
+As of this writing, Markdown has no syntax for specifying the
+dimensions of an image; if this is important to you, you can simply
+use regular HTML `<img>` tags.
+
+
+* * *
+
+
+<h2 id="misc">Miscellaneous</h2>
+
+<h3 id="autolink">Automatic Links</h3>
+
+Markdown supports a shortcut style for creating "automatic" links for URLs and email addresses: simply surround the URL or email address with angle brackets. What this means is that if you want to show the actual text of a URL or email address, and also have it be a clickable link, you can do this:
+
+    <http://example.com/>
+    
+Markdown will turn this into:
+
+    <a href="http://example.com/">http://example.com/</a>
+
+Automatic links for email addresses work similarly, except that
+Markdown will also perform a bit of randomized decimal and hex
+entity-encoding to help obscure your address from address-harvesting
+spambots. For example, Markdown will turn this:
+
+    <address@example.com>
+
+into something like this:
+
+    <a href="&#x6D;&#x61;i&#x6C;&#x74;&#x6F;:&#x61;&#x64;&#x64;&#x72;&#x65;
+    &#115;&#115;&#64;&#101;&#120;&#x61;&#109;&#x70;&#x6C;e&#x2E;&#99;&#111;
+    &#109;">&#x61;&#x64;&#x64;&#x72;&#x65;&#115;&#115;&#64;&#101;&#120;&#x61;
+    &#109;&#x70;&#x6C;e&#x2E;&#99;&#111;&#109;</a>
+
+which will render in a browser as a clickable link to "address@example.com".
+
+(This sort of entity-encoding trick will indeed fool many, if not
+most, address-harvesting bots, but it definitely won't fool all of
+them. It's better than nothing, but an address published in this way
+will probably eventually start receiving spam.)
+
+
+
+<h3 id="backslash">Backslash Escapes</h3>
+
+Markdown allows you to use backslash escapes to generate literal
+characters which would otherwise have special meaning in Markdown's
+formatting syntax. For example, if you wanted to surround a word with
+literal asterisks (instead of an HTML `<em>` tag), you can backslashes
+before the asterisks, like this:
+
+    \*literal asterisks\*
+
+Markdown provides backslash escapes for the following characters:
+
+    \   backslash
+    `   backtick
+    *   asterisk
+    _   underscore
+    {}  curly braces
+    []  square brackets
+    ()  parentheses
+    #   hash mark
+	+	plus sign
+	-	minus sign (hyphen)
+    .   dot
+    !   exclamation mark
+

+
+# Overview
+
+Cobra is a library providing a simple interface to create powerful modern CLI
+interfaces similar to git & go tools.
+
+Cobra is also an application that will generate your application scaffolding to rapidly
+develop a Cobra-based application.
+
+Cobra provides:
+* Easy subcommand-based CLIs: `app server`, `app fetch`, etc.
+* Fully POSIX-compliant flags (including short & long versions)
+* Nested subcommands
+* Global, local and cascading flags
+* Easy generation of applications & commands with `cobra create appname` & `cobra add cmdname`
+* Intelligent suggestions (`app srver`... did you mean `app server`?)
+* Automatic help generation for commands and flags
+* Automatic detailed help for `app help [command]`
+* Automatic help flag recognition of `-h`, `--help`, etc.
+* Automatically generated bash autocomplete for your application
+* Automatically generated man pages for your application
+* Command aliases so you can change things without breaking them
+* The flexibilty to define your own help, usage, etc.
+* Optional tight integration with [viper](http://github.com/spf13/viper) for 12-factor apps
+
+Cobra has an exceptionally clean interface and simple design without needless
+constructors or initialization methods.
+
+Applications built with Cobra commands are designed to be as user-friendly as
+possible. Flags can be placed before or after the command (as long as a
+confusing space isn’t provided). Both short and long flags can be used. A
+command need not even be fully typed.  Help is automatically generated and
+available for the application or for a specific command using either the help
+command or the `--help` flag.
+
+# Concepts
+
+Cobra is built on a structure of commands, arguments & flags.
+
+**Commands** represent actions, **Args** are things and **Flags** are modifiers for those actions.
+
+The best applications will read like sentences when used. Users will know how
+to use the application because they will natively understand how to use it.
+
+The pattern to follow is 
+`APPNAME VERB NOUN --ADJECTIVE.`
+    or
+`APPNAME COMMAND ARG --FLAG`
+
+A few good real world examples may better illustrate this point.
+
+In the following example, 'server' is a command, and 'port' is a flag:
+
+    > hugo serve --port=1313
+
+In this command we are telling Git to clone the url bare.
+
+    > git clone URL --bare
+
+## Commands
+
+Command is the central point of the application. Each interaction that
+the application supports will be contained in a Command. A command can
+have children commands and optionally run an action.
+
+In the example above, 'server' is the command.
+
+A Command has the following structure:
+
+```go
+type Command struct {
+    Use string // The one-line usage message.
+    Short string // The short description shown in the 'help' output.
+    Long string // The long message shown in the 'help <this-command>' output.
+    Run func(cmd *Command, args []string) // Run runs the command.
+}
+```
+
+## Flags
+
+A Flag is a way to modify the behavior of a command. Cobra supports
+fully POSIX-compliant flags as well as the Go [flag package](https://golang.org/pkg/flag/).
+A Cobra command can define flags that persist through to children commands
+and flags that are only available to that command.
+
+In the example above, 'port' is the flag.
+
+Flag functionality is provided by the [pflag
+library](https://github.com/ogier/pflag), a fork of the flag standard library
+which maintains the same interface while adding POSIX compliance.
+
+## Usage
+
+Cobra works by creating a set of commands and then organizing them into a tree.
+The tree defines the structure of the application.
+
+Once each command is defined with its corresponding flags, then the
+tree is assigned to the commander which is finally executed.
+
+# Installing
+Using Cobra is easy. First, use `go get` to install the latest version
+of the library. This command will install the `cobra` generator executible
+along with the library:
+
+    > go get -v github.com/spf13/cobra/cobra
+
+Next, include Cobra in your application:
+
+```go
+import "github.com/spf13/cobra"
+```
+
+# Getting Started
+
+While you are welcome to provide your own organization, typically a Cobra based
+application will follow the following organizational structure.
+
+```
+  ▾ appName/
+    ▾ cmd/
+        add.go
+        your.go
+        commands.go
+        here.go
+      main.go
+```
+
+In a Cobra app, typically the main.go file is very bare. It serves, one purpose, to initialize Cobra.
+
+```go
+package main
+
+import "{pathToYourApp}/cmd"
+
+func main() {
+	if err := cmd.RootCmd.Execute(); err != nil {
+		fmt.Println(err)
+		os.Exit(-1)
+	}
+}
+```
+
+## Using the Cobra Generator
+
+Cobra provides its own program that will create your application and add any
+commands you want. It's the easiest way to incorporate Cobra into your application.
+
+### cobra init
+
+The `cobra init [yourApp]` command will create your initial application code
+for you. It is a very powerful application that will populate your program with
+the right structure so you can immediately enjoy all the benefits of Cobra. It
+will also automatically apply the license you specify to your application.
+
+Cobra init is pretty smart. You can provide it a full path, or simply a path
+similar to what is expected in the import.
+
+```
+cobra init github.com/spf13/newAppName
+```
+
+### cobra add
+
+Once an application is initialized Cobra can create additional commands for you.
+Let's say you created an app and you wanted the following commands for it:
+
+* app serve
+* app config
+* app config create
+
+In your project directory (where your main.go file is) you would run the following:
+
+```
+cobra add serve
+cobra add config
+cobra add create -p 'configCmd'
+```
+
+Once you have run these four commands you would have an app structure that would look like:
+
+```
+  ▾ app/
+    ▾ cmd/
+        serve.go
+        config.go
+        create.go
+      main.go
+```
+
+at this point you can run `go run main.go` and it would run your app. `go run
+main.go serve`, `go run main.go config`, `go run main.go config create` along
+with `go run main.go help serve`, etc would all work.
+
+Obviously you haven't added your own code to these yet, the commands are ready
+for you to give them their tasks. Have fun.
+
+### Configuring the cobra generator
+
+The cobra generator will be easier to use if you provide a simple configuration
+file which will help you eliminate providing a bunch of repeated information in
+flags over and over.
+
+an example ~/.cobra.yaml file:
+
+```yaml
+author: Steve Francia <spf@spf13.com>
+license: MIT
+```
+
+## Manually implementing Cobra
+
+To manually implement cobra you need to create a bare main.go file and a RootCmd file.
+You will optionally provide additional commands as you see fit.
+
+### Create the root command
+
+The root command represents your binary itself.
+
+
+#### Manually create rootCmd
+
+Cobra doesn't require any special constructors. Simply create your commands.
+
+Ideally you place this in app/cmd/root.go:
+
+```go
+var RootCmd = &cobra.Command{
+	Use:   "hugo",
+	Short: "Hugo is a very fast static site generator",
+	Long: `A Fast and Flexible Static Site Generator built with
+                love by spf13 and friends in Go.
+                Complete documentation is available at http://hugo.spf13.com`,
+	Run: func(cmd *cobra.Command, args []string) {
+		// Do Stuff Here
+	},
+}
+```
+
+You will additionally define flags and handle configuration in your init() function.
+
+for example cmd/root.go:
+
+```go
+func init() {
+	cobra.OnInitialize(initConfig)
+	RootCmd.PersistentFlags().StringVar(&cfgFile, "config", "", "config file (default is $HOME/.cobra.yaml)")
+	RootCmd.PersistentFlags().StringVarP(&projectBase, "projectbase", "b", "", "base project directory eg. github.com/spf13/")
+	RootCmd.PersistentFlags().StringP("author", "a", "YOUR NAME", "Author name for copyright attribution")
+	RootCmd.PersistentFlags().StringVarP(&userLicense, "license", "l", "", "Name of license for the project (can provide `licensetext` in config)")
+	RootCmd.PersistentFlags().Bool("viper", true, "Use Viper for configuration")
+	viper.BindPFlag("author", RootCmd.PersistentFlags().Lookup("author"))
+	viper.BindPFlag("projectbase", RootCmd.PersistentFlags().Lookup("projectbase"))
+	viper.BindPFlag("useViper", RootCmd.PersistentFlags().Lookup("viper"))
+	viper.SetDefault("author", "NAME HERE <EMAIL ADDRESS>")
+	viper.SetDefault("license", "apache")
+}
+```
+
+### Create your main.go
+
+With the root command you need to have your main function execute it.
+Execute should be run on the root for clarity, though it can be called on any command.
+
+In a Cobra app, typically the main.go file is very bare. It serves, one purpose, to initialize Cobra.
+
+```go
+package main
+
+import "{pathToYourApp}/cmd"
+
+func main() {
+	if err := cmd.RootCmd.Execute(); err != nil {
+		fmt.Println(err)
+		os.Exit(-1)
+	}
+}
+```
+
+
+### Create additional commands
+
+Additional commands can be defined and typically are each given their own file
+inside of the cmd/ directory.
+
+If you wanted to create a version command you would create cmd/version.go and
+populate it with the following:
+
+```go
+package cmd
+
+import (
+	"github.com/spf13/cobra"
+)
+
+func init() {
+	RootCmd.AddCommand(versionCmd)
+}
+
+var versionCmd = &cobra.Command{
+	Use:   "version",
+	Short: "Print the version number of Hugo",
+	Long:  `All software has versions. This is Hugo's`,
+	Run: func(cmd *cobra.Command, args []string) {
+		fmt.Println("Hugo Static Site Generator v0.9 -- HEAD")
+	},
+}
+```
+
+### Attach command to its parent 
+
+
+If you notice in the above example we attach the command to its parent. In
+this case the parent is the rootCmd. In this example we are attaching it to the
+root, but commands can be attached at any level.
+
+```go
+RootCmd.AddCommand(versionCmd)
+```
+
+### Remove a command from its parent
+
+Removing a command is not a common action in simple programs, but it allows 3rd
+parties to customize an existing command tree.
+
+In this example, we remove the existing `VersionCmd` command of an existing
+root command, and we replace it with our own version:
+
+```go
+mainlib.RootCmd.RemoveCommand(mainlib.VersionCmd)
+mainlib.RootCmd.AddCommand(versionCmd)
+```
+
+## Working with Flags
+
+Flags provide modifiers to control how the action command operates.
+
+### Assign flags to a command
+
+Since the flags are defined and used in different locations, we need to
+define a variable outside with the correct scope to assign the flag to
+work with.
+
+```go
+var Verbose bool
+var Source string
+```
+
+There are two different approaches to assign a flag.
+
+### Persistent Flags
+
+A flag can be 'persistent' meaning that this flag will be available to the
+command it's assigned to as well as every command under that command. For
+global flags, assign a flag as a persistent flag on the root.
+
+```go
+RootCmd.PersistentFlags().BoolVarP(&Verbose, "verbose", "v", false, "verbose output")
+```
+
+### Local Flags
+
+A flag can also be assigned locally which will only apply to that specific command.
+
+```go
+RootCmd.Flags().StringVarP(&Source, "source", "s", "", "Source directory to read from")
+```
+
+
+## Example
+
+In the example below, we have defined three commands. Two are at the top level
+and one (cmdTimes) is a child of one of the top commands. In this case the root
+is not executable meaning that a subcommand is required. This is accomplished
+by not providing a 'Run' for the 'rootCmd'.
+
+We have only defined one flag for a single command.
+
+More documentation about flags is available at https://github.com/spf13/pflag
+
+```go
+package main
+
+import (
+	"fmt"
+	"strings"
+
+	"github.com/spf13/cobra"
+)
+
+func main() {
+
+	var echoTimes int
+
+	var cmdPrint = &cobra.Command{
+		Use:   "print [string to print]",
+		Short: "Print anything to the screen",
+		Long: `print is for printing anything back to the screen.
+            For many years people have printed back to the screen.
+            `,
+		Run: func(cmd *cobra.Command, args []string) {
+			fmt.Println("Print: " + strings.Join(args, " "))
+		},
+	}
+
+	var cmdEcho = &cobra.Command{
+		Use:   "echo [string to echo]",
+		Short: "Echo anything to the screen",
+		Long: `echo is for echoing anything back.
+            Echo works a lot like print, except it has a child command.
+            `,
+		Run: func(cmd *cobra.Command, args []string) {
+			fmt.Println("Print: " + strings.Join(args, " "))
+		},
+	}
+
+	var cmdTimes = &cobra.Command{
+		Use:   "times [# times] [string to echo]",
+		Short: "Echo anything to the screen more times",
+		Long: `echo things multiple times back to the user by providing
+            a count and a string.`,
+		Run: func(cmd *cobra.Command, args []string) {
+			for i := 0; i < echoTimes; i++ {
+				fmt.Println("Echo: " + strings.Join(args, " "))
+			}
+		},
+	}
+
+	cmdTimes.Flags().IntVarP(&echoTimes, "times", "t", 1, "times to echo the input")
+
+	var rootCmd = &cobra.Command{Use: "app"}
+	rootCmd.AddCommand(cmdPrint, cmdEcho)
+	cmdEcho.AddCommand(cmdTimes)
+	rootCmd.Execute()
+}
+```

+
+## The Help Command
+
+Cobra automatically adds a help command to your application when you have subcommands.
+This will be called when a user runs 'app help'. Additionally, help will also
+support all other commands as input. Say, for instance, you have a command called
+'create' without any additional configuration; Cobra will work when 'app help
+create' is called.  Every command will automatically have the '--help' flag added.
+
+### Example
+
+The following output is automatically generated by Cobra. Nothing beyond the
+command and flag definitions are needed.
+
+    > hugo help
+    
+    hugo is the main command, used to build your Hugo site.
+    
+    Hugo is a Fast and Flexible Static Site Generator

+      -D, --buildDrafts[=false]: include content marked as draft
+      -F, --buildFuture[=false]: include content with publishdate in the future
+          --cacheDir="": filesystem path to cache directory. Defaults: $TMPDIR/hugo_cache/
+          --canonifyURLs[=false]: if true, all relative URLs will be canonicalized using baseURL

+    
+    Use "hugo [command] --help" for more information about a command.
+
+
+Help is just a command like any other. There is no special logic or behavior
+around it. In fact, you can provide your own if you want.
+
+### Defining your own help
+
+You can provide your own Help command or you own template for the default command to use.
+
+The default help command is
+
+```go
+func (c *Command) initHelp() {
+	if c.helpCommand == nil {
+		c.helpCommand = &Command{
+			Use:   "help [command]",
+			Short: "Help about any command",
+			Long: `Help provides help for any command in the application.
+        Simply type ` + c.Name() + ` help [path to command] for full details.`,
+			Run: c.HelpFunc(),
+		}
+	}
+	c.AddCommand(c.helpCommand)
+}
+```
+
+You can provide your own command, function or template through the following methods:
+
+```go
+command.SetHelpCommand(cmd *Command)
+
+command.SetHelpFunc(f func(*Command, []string))
+
+command.SetHelpTemplate(s string)
+```
+
+The latter two will also apply to any children commands.
+
+## Usage
+
+When the user provides an invalid flag or invalid command, Cobra responds by
+showing the user the 'usage'.
+
+### Example
+You may recognize this from the help above. That's because the default help
+embeds the usage as part of its output.
+
+    Usage:
+      hugo [flags]
+      hugo [command]
+    
+    Available Commands:
+      server          Hugo runs its own webserver to render the files
+      version         Print the version number of Hugo
+      config          Print the site configuration
+      check           Check content in the source directory
+      benchmark       Benchmark hugo by building a site a number of times.
+      convert         Convert your content to different formats
+      new             Create new content for your site
+      list            Listing out various types of content
+      undraft         Undraft changes the content's draft status from 'True' to 'False'
+      genautocomplete Generate shell autocompletion script for Hugo
+      gendoc          Generate Markdown documentation for the Hugo CLI.
+      genman          Generate man page for Hugo
+      import          Import your site from others.
+    
+    Flags:
+      -b, --baseURL="": hostname (and path) to the root, e.g. http://spf13.com/
+      -D, --buildDrafts[=false]: include content marked as draft
+      -F, --buildFuture[=false]: include content with publishdate in the future
+          --cacheDir="": filesystem path to cache directory. Defaults: $TMPDIR/hugo_cache/
+          --canonifyURLs[=false]: if true, all relative URLs will be canonicalized using baseURL
+          --config="": config file (default is path/config.yaml|json|toml)
+      -d, --destination="": filesystem path to write files to
+          --disableRSS[=false]: Do not build RSS files
+          --disableSitemap[=false]: Do not build Sitemap file
+          --editor="": edit new content with this editor, if provided

+          --preserveTaxonomyNames[=false]: Preserve taxonomy names as written ("Gérard Depardieu" vs "gerard-depardieu")
+      -s, --source="": filesystem path to read files relative from
+          --stepAnalysis[=false]: display memory and timing of different steps of the program
+      -t, --theme="": theme to use (located in /themes/THEMENAME/)
+          --uglyURLs[=false]: if true, use /filename.html instead of /filename/
+      -v, --verbose[=false]: verbose output
+          --verboseLog[=false]: verbose logging
+      -w, --watch[=false]: watch filesystem for changes and recreate as needed
+
+### Defining your own usage
+You can provide your own usage function or template for Cobra to use.
+
+The default usage function is:
+
+```go
+return func(c *Command) error {
+	err := tmpl(c.Out(), c.UsageTemplate(), c)
+	return err
+}
+```
+
+Like help, the function and template are overridable through public methods:
+
+```go
+command.SetUsageFunc(f func(*Command) error)
+
+command.SetUsageTemplate(s string)
+```
+
+## PreRun or PostRun Hooks
+
+It is possible to run functions before or after the main `Run` function of your command. The `PersistentPreRun` and `PreRun` functions will be executed before `Run`. `PersistentPostRun` and `PostRun` will be executed after `Run`.  The `Persistent*Run` functions will be inherrited by children if they do not declare their own.  These function are run in the following order:
+
+- `PersistentPreRun`
+- `PreRun`
+- `Run`
+- `PostRun`
+- `PersistentPostRun`
+
+An example of two commands which use all of these features is below.  When the subcommand is executed, it will run the root command's `PersistentPreRun` but not the root command's `PersistentPostRun`:
+
+```go
+package main
+
+import (
+	"fmt"
+
+	"github.com/spf13/cobra"
+)
+
+func main() {
+
+	var rootCmd = &cobra.Command{
+		Use:   "root [sub]",
+		Short: "My root command",
+		PersistentPreRun: func(cmd *cobra.Command, args []string) {
+			fmt.Printf("Inside rootCmd PersistentPreRun with args: %v\n", args)
+		},
+		PreRun: func(cmd *cobra.Command, args []string) {
+			fmt.Printf("Inside rootCmd PreRun with args: %v\n", args)
+		},
+		Run: func(cmd *cobra.Command, args []string) {
+			fmt.Printf("Inside rootCmd Run with args: %v\n", args)
+		},
+		PostRun: func(cmd *cobra.Command, args []string) {
+			fmt.Printf("Inside rootCmd PostRun with args: %v\n", args)
+		},
+		PersistentPostRun: func(cmd *cobra.Command, args []string) {
+			fmt.Printf("Inside rootCmd PersistentPostRun with args: %v\n", args)
+		},
+	}
+
+	var subCmd = &cobra.Command{
+		Use:   "sub [no options!]",
+		Short: "My subcommand",
+		PreRun: func(cmd *cobra.Command, args []string) {
+			fmt.Printf("Inside subCmd PreRun with args: %v\n", args)
+		},
+		Run: func(cmd *cobra.Command, args []string) {
+			fmt.Printf("Inside subCmd Run with args: %v\n", args)
+		},
+		PostRun: func(cmd *cobra.Command, args []string) {
+			fmt.Printf("Inside subCmd PostRun with args: %v\n", args)
+		},
+		PersistentPostRun: func(cmd *cobra.Command, args []string) {
+			fmt.Printf("Inside subCmd PersistentPostRun with args: %v\n", args)
+		},
+	}
+
+	rootCmd.AddCommand(subCmd)
+
+	rootCmd.SetArgs([]string{""})
+	_ = rootCmd.Execute()
+	fmt.Print("\n")
+	rootCmd.SetArgs([]string{"sub", "arg1", "arg2"})
+	_ = rootCmd.Execute()
+}
+```
+
+
+## Alternative Error Handling
+
+Cobra also has functions where the return signature is an error. This allows for errors to bubble up to the top, providing a way to handle the errors in one location. The current list of functions that return an error is:
+
+* PersistentPreRunE
+* PreRunE
+* RunE
+* PostRunE
+* PersistentPostRunE
+
+**Example Usage using RunE:**
+
+```go
+package main
+
+import (
+	"errors"
+	"log"
+
+	"github.com/spf13/cobra"
+)
+
+func main() {
+	var rootCmd = &cobra.Command{
+		Use:   "hugo",
+		Short: "Hugo is a very fast static site generator",
+		Long: `A Fast and Flexible Static Site Generator built with
+                love by spf13 and friends in Go.
+                Complete documentation is available at http://hugo.spf13.com`,
+		RunE: func(cmd *cobra.Command, args []string) error {
+			// Do Stuff Here
+			return errors.New("some random error")
+		},
+	}
+
+	if err := rootCmd.Execute(); err != nil {
+		log.Fatal(err)
+	}
+}
+```
+
+## Suggestions when "unknown command" happens
+
+Cobra will print automatic suggestions when "unknown command" errors happen. This allows Cobra to behave similarly to the `git` command when a typo happens. For example:
+
+```
+$ hugo srever
+Error: unknown command "srever" for "hugo"
+
+Did you mean this?
+        server
+
+Run 'hugo --help' for usage.
+```
+
+Suggestions are automatic based on every subcommand registered and use an implementation of [Levenshtein distance](http://en.wikipedia.org/wiki/Levenshtein_distance). Every registered command that matches a minimum distance of 2 (ignoring case) will be displayed as a suggestion.
+
+If you need to disable suggestions or tweak the string distance in your command, use:
+
+```go
+command.DisableSuggestions = true
+```
+
+or
+
+```go
+command.SuggestionsMinimumDistance = 1
+```
+
+You can also explicitly set names for which a given command will be suggested using the `SuggestFor` attribute. This allows suggestions for strings that are not close in terms of string distance, but makes sense in your set of commands and for some which you don't want aliases. Example:
+
+```
+$ kubectl remove
+Error: unknown command "remove" for "kubectl"
+
+Did you mean this?
+        delete
+
+Run 'kubectl help' for usage.
+```
+
+## Generating Markdown-formatted documentation for your command
+
+Cobra can generate a Markdown-formatted document based on the subcommands, flags, etc. A simple example of how to do this for your command can be found in [Markdown Docs](md_docs.md).
+
+## Generating man pages for your command
+
+Cobra can generate a man page based on the subcommands, flags, etc. A simple example of how to do this for your command can be found in [Man Docs](man_docs.md).
+
+## Generating bash completions for your command
+
+Cobra can generate a bash-completion file. If you add more information to your command, these completions can be amazingly powerful and flexible.  Read more about it in [Bash Completions](bash_completions.md).
+
+## Debugging
+
+Cobra provides a ‘DebugFlags’ method on a command which, when called, will print
+out everything Cobra knows about the flags for each command.
+
+### Example
+
+```go
+command.DebugFlags()
+```
+

+# Generating Bash Completions For Your Own cobra.Command
+
+Generating bash completions from a cobra command is incredibly easy. An actual program which does so for the kubernetes kubectl binary is as follows:
+
+```go
+package main
+
+import (
+        "io/ioutil"
+        "os"
+
+        "github.com/GoogleCloudPlatform/kubernetes/pkg/kubectl/cmd"
+)
+
+func main() {
+        kubectl := cmd.NewFactory(nil).NewKubectlCommand(os.Stdin, ioutil.Discard, ioutil.Discard)
+        kubectl.GenBashCompletionFile("out.sh")
+}
+```
+
+That will get you completions of subcommands and flags. If you make additional annotations to your code, you can get even more intelligent and flexible behavior.
+
+## Creating your own custom functions
+
+Some more actual code that works in kubernetes:
+
+```bash
+const (
+        bash_completion_func = `__kubectl_parse_get()
+{
+    local kubectl_output out
+    if kubectl_output=$(kubectl get --no-headers "$1" 2>/dev/null); then
+        out=($(echo "${kubectl_output}" | awk '{print $1}'))
+        COMPREPLY=( $( compgen -W "${out[*]}" -- "$cur" ) )
+    fi
+}
+
+__kubectl_get_resource()
+{
+    if [[ ${#nouns[@]} -eq 0 ]]; then
+        return 1
+    fi
+    __kubectl_parse_get ${nouns[${#nouns[@]} -1]}
+    if [[ $? -eq 0 ]]; then
+        return 0
+    fi
+}
+
+__custom_func() {
+    case ${last_command} in
+        kubectl_get | kubectl_describe | kubectl_delete | kubectl_stop)
+            __kubectl_get_resource
+            return
+            ;;
+        *)
+            ;;
+    esac
+}
+`)
+```
+
+And then I set that in my command definition:
+
+```go
+cmds := &cobra.Command{
+	Use:   "kubectl",
+	Short: "kubectl controls the Kubernetes cluster manager",
+	Long: `kubectl controls the Kubernetes cluster manager.
+
+Find more information at https://github.com/GoogleCloudPlatform/kubernetes.`,
+	Run: runHelp,
+	BashCompletionFunction: bash_completion_func,
+}
+```
+
+The `BashCompletionFunction` option is really only valid/useful on the root command. Doing the above will cause `__custom_func()` to be called when the built in processor was unable to find a solution. In the case of kubernetes a valid command might look something like `kubectl get pod [mypod]`. If you type `kubectl get pod [tab][tab]` the `__customc_func()` will run because the cobra.Command only understood "kubectl" and "get." `__custom_func()` will see that the cobra.Command is "kubectl_get" and will thus call another helper `__kubectl_get_resource()`.  `__kubectl_get_resource` will look at the 'nouns' collected. In our example the only noun will be `pod`.  So it will call `__kubectl_parse_get pod`.  `__kubectl_parse_get` will actually call out to kubernetes and get any pods.  It will then set `COMPREPLY` to valid pods!
+
+## Have the completions code complete your 'nouns'
+
+In the above example "pod" was assumed to already be typed. But if you want `kubectl get [tab][tab]` to show a list of valid "nouns" you have to set them. Simplified code from `kubectl get` looks like:
+
+```go
+validArgs []string = { "pods", "nodes", "services", "replicationControllers" }
+
+cmd := &cobra.Command{
+	Use:     "get [(-o|--output=)json|yaml|template|...] (RESOURCE [NAME] | RESOURCE/NAME ...)",
+	Short:   "Display one or many resources",
+	Long:    get_long,
+	Example: get_example,
+	Run: func(cmd *cobra.Command, args []string) {
+		err := RunGet(f, out, cmd, args)
+		util.CheckErr(err)
+	},
+	ValidArgs: validArgs,
+}
+```
+
+Notice we put the "ValidArgs" on the "get" subcommand. Doing so will give results like
+
+```bash
+# kubectl get [tab][tab]
+nodes                 pods                    replicationControllers  services
+```
+
+## Mark flags as required
+
+Most of the time completions will only show subcommands. But if a flag is required to make a subcommand work, you probably want it to show up when the user types [tab][tab].  Marking a flag as 'Required' is incredibly easy.
+
+```go
+cmd.MarkFlagRequired("pod")
+cmd.MarkFlagRequired("container")
+```
+
+and you'll get something like
+
+```bash
+# kubectl exec [tab][tab][tab]
+-c            --container=  -p            --pod=  
+```
+
+# Specify valid filename extensions for flags that take a filename
+
+In this example we use --filename= and expect to get a json or yaml file as the argument. To make this easier we annotate the --filename flag with valid filename extensions.
+
+```go
+	annotations := []string{"json", "yaml", "yml"}
+	annotation := make(map[string][]string)
+	annotation[cobra.BashCompFilenameExt] = annotations
+
+	flag := &pflag.Flag{
+		Name:        "filename",
+		Shorthand:   "f",
+		Usage:       usage,
+		Value:       value,
+		DefValue:    value.String(),
+		Annotations: annotation,
+	}
+	cmd.Flags().AddFlag(flag)
+```
+
+Now when you run a command with this filename flag you'll get something like
+
+```bash
+# kubectl create -f 
+test/                         example/                      rpmbuild/
+hello.yml                     test.json
+```
+
+So while there are many other files in the CWD it only shows me subdirs and those with valid extensions.

+      source, and configuration files.
+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain
+      separable from, or merely link (or bind by name) to the interfaces of,
+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"
+      means any form of electronic, verbal, or written communication sent
+      to the Licensor or its representatives, including but not limited to
+      communication on electronic mailing lists, source code control systems,
+      and issue tracking systems that are managed by, or on behalf of, the
+      Licensor for the purpose of discussing and improving the Work, but
+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.  We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors.  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights.  Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received.  You must make sure that they, too, receive
+or can get the source code.  And you must show them these terms so they
+know their rights.
+
+  Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+  For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software.  For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+  Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so.  This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software.  The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable.  Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products.  If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+  Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary.  To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Use with the GNU Affero General Public License.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software: you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation, either version 3 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program.  If not, see <http://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+  If the program does terminal interaction, make it output a short
+notice like this when it starts in an interactive mode:
+
+    <program>  Copyright (C) <year>  <name of author>
+    This program comes with ABSOLUTELY NO WARRANTY; for details type 'show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type 'show c' for details.
+
+The hypothetical commands 'show w' and 'show c' should show the appropriate
+parts of the General Public License.  Of course, your program's commands
+might be different; for a GUI interface, you would use an "about box".
+
+  You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU GPL, see
+<http://www.gnu.org/licenses/>.
+
+  The GNU General Public License does not permit incorporating your program
+into proprietary programs.  If your program is a subroutine library, you
+may consider it more useful to permit linking proprietary applications with
+the library.  If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.  But first, please read
+<http://www.gnu.org/philosophy/why-not-lgpl.html>.

+# Generating Man Pages For Your Own cobra.Command
+
+Generating man pages from a cobra command is incredibly easy. An example is as follows:
+
+```go
+package main
+
+import (
+	"github.com/spf13/cobra"
+)
+
+func main() {
+	cmd := &cobra.Command{
+		Use:   "test",
+		Short: "my test program",
+	}
+	header := &cobra.GenManHeader{
+		Title: "MINE",
+		Section: "3",
+	}
+	cmd.GenManTree(header, "/tmp")
+}
+```
+
+That will get you a man page `/tmp/test.1`

+# Generating Markdown Docs For Your Own cobra.Command
+
+## Generate markdown docs for the entire command tree
+
+This program can actually generate docs for the kubectl command in the kubernetes project
+
+```go
+package main
+
+import (
+	"io/ioutil"
+	"os"
+
+	"github.com/GoogleCloudPlatform/kubernetes/pkg/kubectl/cmd"
+	"github.com/spf13/cobra"
+)
+
+func main() {
+	kubectl := cmd.NewFactory(nil).NewKubectlCommand(os.Stdin, ioutil.Discard, ioutil.Discard)
+	cobra.GenMarkdownTree(kubectl, "./")
+}
+```
+
+This will generate a whole series of files, one for each command in the tree, in the directory specified (in this case "./")
+
+## Generate markdown docs for a single command
+
+You may wish to have more control over the output, or only generate for a single command, instead of the entire command tree. If this is the case you may prefer to `GenMarkdown` instead of `GenMarkdownTree`
+
+```go
+	out := new(bytes.Buffer)
+	cobra.GenMarkdown(cmd, out)
+```
+
+This will write the markdown doc for ONLY "cmd" into the out, buffer.
+
+## Customize the output
+
+Both `GenMarkdown` and `GenMarkdownTree` have alternate versions with callbacks to get some control of the output:
+
+```go
+func GenMarkdownTreeCustom(cmd *Command, dir string, filePrepender func(string) string, linkHandler func(string) string) {
+    //...
+}
+```
+
+```go
+func GenMarkdownCustom(cmd *Command, out *bytes.Buffer, linkHandler func(string) string) {
+    //...
+}
+```
+
+The `filePrepender` will prepend the return value given the full filepath to the rendered Markdown file. A common use case is to add front matter to use the generated documentation with [Hugo](http://gohugo.io/):
+
+```go
+const fmTemplate = `---
+date: %s
+title: "%s"
+slug: %s
+url: %s
+---
+`
+
+filePrepender := func(filename string) string {
+	now := time.Now().Format(time.RFC3339)
+	name := filepath.Base(filename)
+	base := strings.TrimSuffix(name, path.Ext(name))
+	url := "/commands/" + strings.ToLower(base) + "/"
+	return fmt.Sprintf(fmTemplate, now, strings.Replace(base, "_", " ", -1), base, url)
+}
+```
+
+The `linkHandler` can be used to customize the rendered internal links to the commands, given a filename:
+
+```go
+linkHandler := func(name string) string {
+	base := strings.TrimSuffix(name, path.Ext(name))
+	return "/commands/" + strings.ToLower(base) + "/"
+}
+```
+

+[![Build Status](https://travis-ci.org/spf13/pflag.svg?branch=master)](https://travis-ci.org/spf13/pflag)
+
+## Description
+
+pflag is a drop-in replacement for Go's flag package, implementing
+POSIX/GNU-style --flags.
+
+pflag is compatible with the [GNU extensions to the POSIX recommendations
+for command-line options][1]. For a more precise description, see the
+"Command-line flag syntax" section below.
+
+[1]: http://www.gnu.org/software/libc/manual/html_node/Argument-Syntax.html
+
+pflag is available under the same style of BSD license as the Go language,
+which can be found in the LICENSE file.
+
+## Installation
+
+pflag is available using the standard `go get` command.
+
+Install by running:
+
+    go get github.com/spf13/pflag
+
+Run tests by running:
+
+    go test github.com/spf13/pflag
+
+## Usage
+
+pflag is a drop-in replacement of Go's native flag package. If you import
+pflag under the name "flag" then all code should continue to function
+with no changes.
+
+``` go
+import flag "github.com/spf13/pflag"
+```
+
+There is one exception to this: if you directly instantiate the Flag struct
+there is one more field "Shorthand" that you will need to set.
+Most code never instantiates this struct directly, and instead uses
+functions such as String(), BoolVar(), and Var(), and is therefore
+unaffected.
+
+Define flags using flag.String(), Bool(), Int(), etc.
+
+This declares an integer flag, -flagname, stored in the pointer ip, with type *int.
+
+``` go
+var ip *int = flag.Int("flagname", 1234, "help message for flagname")
+```
+
+If you like, you can bind the flag to a variable using the Var() functions.
+
+``` go
+var flagvar int
+func init() {
+    flag.IntVar(&flagvar, "flagname", 1234, "help message for flagname")
+}
+```
+
+Or you can create custom flags that satisfy the Value interface (with
+pointer receivers) and couple them to flag parsing by
+
+``` go
+flag.Var(&flagVal, "name", "help message for flagname")
+```
+
+For such flags, the default value is just the initial value of the variable.
+
+After all flags are defined, call
+
+``` go
+flag.Parse()
+```
+
+to parse the command line into the defined flags.
+
+Flags may then be used directly. If you're using the flags themselves,
+they are all pointers; if you bind to variables, they're values.
+
+``` go
+fmt.Println("ip has value ", *ip)
+fmt.Println("flagvar has value ", flagvar)
+```
+
+There are helpers function to get values later if you have the FlagSet but
+it was difficult to keep up with all of the the flag pointers in your code.
+If you have a pflag.FlagSet with a flag called 'flagname' of type int you
+can use GetInt() to get the int value. But notice that 'flagname' must exist
+and it must be an int. GetString("flagname") will fail.
+
+``` go
+i, err := flagset.GetInt("flagname")
+```
+
+After parsing, the arguments after the flag are available as the
+slice flag.Args() or individually as flag.Arg(i).
+The arguments are indexed from 0 through flag.NArg()-1.
+
+The pflag package also defines some new functions that are not in flag,
+that give one-letter shorthands for flags. You can use these by appending
+'P' to the name of any function that defines a flag.
+
+``` go
+var ip = flag.IntP("flagname", "f", 1234, "help message")
+var flagvar bool
+func init() {
+    flag.BoolVarP("boolname", "b", true, "help message")
+}
+flag.VarP(&flagVar, "varname", "v", 1234, "help message")
+```
+
+Shorthand letters can be used with single dashes on the command line.
+Boolean shorthand flags can be combined with other shorthand flags.
+
+The default set of command-line flags is controlled by
+top-level functions.  The FlagSet type allows one to define
+independent sets of flags, such as to implement subcommands
+in a command-line interface. The methods of FlagSet are
+analogous to the top-level functions for the command-line
+flag set.
+
+## Setting no option default values for flags
+
+After you create a flag it is possible to set the pflag.NoOptDefVal for
+the given flag. Doing this changes the meaning of the flag slightly. If
+a flag has a NoOptDefVal and the flag is set on the command line without
+an option the flag will be set to the NoOptDefVal. For example given:
+
+``` go
+var ip = flag.IntP("flagname", "f", 1234, "help message")
+flag.Lookup("flagname").NoOptDefVal = "4321"
+```
+
+Would result in something like
+
+| Parsed Arguments | Resulting Value |
+| -------------    | -------------   |
+| --flagname=1357  | ip=1357         |
+| --flagname       | ip=4321         |
+| [nothing]        | ip=1234         |
+
+## Command line flag syntax
+
+```
+--flag    // boolean flags, or flags with no option default values
+--flag x  // only on flags without a default value
+--flag=x
+```
+
+Unlike the flag package, a single dash before an option means something
+different than a double dash. Single dashes signify a series of shorthand
+letters for flags. All but the last shorthand letter must be boolean flags
+or a flag with a default value
+
+```
+// boolean or flags where the 'no option default value' is set
+-f
+-f=true
+-abc
+but
+-b true is INVALID
+
+// non-boolean and flags without a 'no option default value'
+-n 1234
+-n=1234
+-n1234
+
+// mixed
+-abcs "hello"
+-absd="hello"
+-abcs1234
+```
+
+Flag parsing stops after the terminator "--". Unlike the flag package,
+flags can be interspersed with arguments anywhere on the command line
+before this terminator.
+
+Integer flags accept 1234, 0664, 0x1234 and may be negative.
+Boolean flags (in their long form) accept 1, 0, t, f, true, false,
+TRUE, FALSE, True, False.
+Duration flags accept any input valid for time.ParseDuration.
+
+## Mutating or "Normalizing" Flag names
+
+It is possible to set a custom flag name 'normalization function.' It allows flag names to be mutated both when created in the code and when used on the command line to some 'normalized' form. The 'normalized' form is used for comparison. Two examples of using the custom normalization func follow.
+
+**Example #1**: You want -, _, and . in flags to compare the same. aka --my-flag == --my_flag == --my.flag
+
+``` go
+func wordSepNormalizeFunc(f *pflag.FlagSet, name string) pflag.NormalizedName {
+	from := []string{"-", "_"}
+	to := "."
+	for _, sep := range from {
+		name = strings.Replace(name, sep, to, -1)
+	}
+	return pflag.NormalizedName(name)
+}
+
+myFlagSet.SetNormalizeFunc(wordSepNormalizeFunc)
+```
+
+**Example #2**: You want to alias two flags. aka --old-flag-name == --new-flag-name
+
+``` go
+func aliasNormalizeFunc(f *pflag.FlagSet, name string) pflag.NormalizedName {
+	switch name {
+	case "old-flag-name":
+		name = "new-flag-name"
+		break
+	}
+	return pflag.NormalizedName(name)
+}
+
+myFlagSet.SetNormalizeFunc(aliasNormalizeFunc)
+```
+
+## Deprecating a flag or its shorthand
+It is possible to deprecate a flag, or just its shorthand. Deprecating a flag/shorthand hides it from help text and prints a usage message when the deprecated flag/shorthand is used.
+
+**Example #1**: You want to deprecate a flag named "badflag" as well as inform the users what flag they should use instead.
+```go
+// deprecate a flag by specifying its name and a usage message
+flags.MarkDeprecated("badflag", "please use --good-flag instead")
+```
+This hides "badflag" from help text, and prints `Flag --badflag has been deprecated, please use --good-flag instead` when "badflag" is used.
+
+**Example #2**: You want to keep a flag name "noshorthandflag" but deprecate its shortname "n".
+```go
+// deprecate a flag shorthand by specifying its flag name and a usage message
+flags.MarkShorthandDeprecated("noshorthandflag", "please use --noshorthandflag only")
+```
+This hides the shortname "n" from help text, and prints `Flag shorthand -n has been deprecated, please use --noshorthandflag only` when the shorthand "n" is used.
+
+Note that usage message is essential here, and it should not be empty.
+
+## Hidden flags
+It is possible to mark a flag as hidden, meaning it will still function as normal, however will not show up in usage/help text.
+
+**Example**: You have a flag named "secretFlag" that you need for internal use only and don't want it showing up in help text, or for its usage text to be available.
+```go
+// hide a flag by specifying its name
+flags.MarkHidden("secretFlag")
+```
+
+## More info
+
+You can see the full reference documentation of the pflag package
+[at godoc.org][3], or through go's standard documentation system by
+running `godoc -http=:6060` and browsing to
+[http://localhost:6060/pkg/github.com/ogier/pflag][2] after
+installation.

+Package pflag is a drop-in replacement for Go's flag package, implementing
+POSIX/GNU-style --flags.
+
+pflag is compatible with the GNU extensions to the POSIX recommendations
+for command-line options. See
+http://www.gnu.org/software/libc/manual/html_node/Argument-Syntax.html
+
+Usage:
+
+pflag is a drop-in replacement of Go's native flag package. If you import
+pflag under the name "flag" then all code should continue to function
+with no changes.
+
+	import flag "github.com/ogier/pflag"
+
+	There is one exception to this: if you directly instantiate the Flag struct
+there is one more field "Shorthand" that you will need to set.
+Most code never instantiates this struct directly, and instead uses
+functions such as String(), BoolVar(), and Var(), and is therefore
+unaffected.
+
+Define flags using flag.String(), Bool(), Int(), etc.
+
+This declares an integer flag, -flagname, stored in the pointer ip, with type *int.
+	var ip = flag.Int("flagname", 1234, "help message for flagname")
+If you like, you can bind the flag to a variable using the Var() functions.
+	var flagvar int
+	func init() {
+		flag.IntVar(&flagvar, "flagname", 1234, "help message for flagname")
+	}
+Or you can create custom flags that satisfy the Value interface (with
+pointer receivers) and couple them to flag parsing by
+	flag.Var(&flagVal, "name", "help message for flagname")
+For such flags, the default value is just the initial value of the variable.
+
+After all flags are defined, call
+	flag.Parse()
+to parse the command line into the defined flags.
+
+Flags may then be used directly. If you're using the flags themselves,
+they are all pointers; if you bind to variables, they're values.
+	fmt.Println("ip has value ", *ip)
+	fmt.Println("flagvar has value ", flagvar)
+
+After parsing, the arguments after the flag are available as the
+slice flag.Args() or individually as flag.Arg(i).
+The arguments are indexed from 0 through flag.NArg()-1.
+
+The pflag package also defines some new functions that are not in flag,
+that give one-letter shorthands for flags. You can use these by appending
+'P' to the name of any function that defines a flag.
+	var ip = flag.IntP("flagname", "f", 1234, "help message")
+	var flagvar bool
+	func init() {
+		flag.BoolVarP("boolname", "b", true, "help message")
+	}
+	flag.VarP(&flagVar, "varname", "v", 1234, "help message")
+Shorthand letters can be used with single dashes on the command line.
+Boolean shorthand flags can be combined with other shorthand flags.
+
+Command line flag syntax:
+	--flag    // boolean flags only
+	--flag=x
+
+Unlike the flag package, a single dash before an option means something
+different than a double dash. Single dashes signify a series of shorthand
+letters for flags. All but the last shorthand letter must be boolean flags.
+	// boolean flags
+	-f
+	-abc
+	// non-boolean flags
+	-n 1234
+	-Ifile
+	// mixed
+	-abcs "hello"
+	-abcn1234
+
+Flag parsing stops after the terminator "--". Unlike the flag package,
+flags can be interspersed with arguments anywhere on the command line
+before this terminator.
+
+Integer flags accept 1234, 0664, 0x1234 and may be negative.
+Boolean flags (in their long form) accept 1, 0, t, f, true, false,
+TRUE, FALSE, True, False.
+Duration flags accept any input valid for time.ParseDuration.
+
+The default set of command-line flags is controlled by
+top-level functions.  The FlagSet type allows one to define
+independent sets of flags, such as to implement subcommands
+in a command-line interface. The methods of FlagSet are
+analogous to the top-level functions for the command-line
+flag set.
