+	Package proto converts data structures to and from the wire format of
+	protocol buffers.  It works in concert with the Go source code generated
+	for .proto files by the protocol compiler.
+
+	A summary of the properties of the protocol buffer interface
+	for a protocol buffer variable v:
+
+	  - Names are turned from camel_case to CamelCase for export.
+	  - There are no methods on v to set fields; just treat
+	  	them as structure fields.
+	  - There are getters that return a field's value if set,
+		and return the field's default value if unset.
+		The getters work even if the receiver is a nil message.
+	  - The zero value for a struct is its correct initialization state.
+		All desired fields must be set before marshaling.
+	  - A Reset() method will restore a protobuf struct to its zero state.
+	  - Non-repeated fields are pointers to the values; nil means unset.
+		That is, optional or required field int32 f becomes F *int32.
+	  - Repeated fields are slices.
+	  - Helper functions are available to aid the setting of fields.
+		Helpers for getting values are superseded by the
+		GetFoo methods and their use is deprecated.
+			msg.Foo = proto.String("hello") // set field
+	  - Constants are defined to hold the default values of all fields that
+		have them.  They have the form Default_StructName_FieldName.
+		Because the getter methods handle defaulted values,
+		direct use of these constants should be rare.
+	  - Enums are given type names and maps from names to values.
+		Enum values are prefixed with the enum's type name. Enum types have
+		a String method, and a Enum method to assist in message construction.
+	  - Nested groups and enums have type names prefixed with the name of
+	  	the surrounding message type.
+	  - Extensions are given descriptor names that start with E_,
+		followed by an underscore-delimited list of the nested messages
+		that contain it (if any) followed by the CamelCased name of the
+		extension field itself.  HasExtension, ClearExtension, GetExtension
+		and SetExtension are functions for manipulating extensions.
+	  - Marshal and Unmarshal are functions to encode and decode the wire format.
+
+	The simplest way to describe this is to see an example.
+	Given file test.proto, containing
+
+		package example;
+
+		enum FOO { X = 17; };
+
+		message Test {
+		  required string label = 1;
+		  optional int32 type = 2 [default=77];
+		  repeated int64 reps = 3;
+		  optional group OptionalGroup = 4 {
+		    required string RequiredField = 5;
+		  }
+		}
