+	//   [g,h)  [ 4, 0, 2, 0, 3 ]  The number (1).
+	//
+	// Notes:
+	// - A location may refer to a repeated field itself (i.e. not to any
+	//   particular index within it).  This is used whenever a set of elements are
+	//   logically enclosed in a single code segment.  For example, an entire
+	//   extend block (possibly containing multiple extension definitions) will
+	//   have an outer location whose path refers to the "extensions" repeated
+	//   field without an index.
+	// - Multiple locations may have the same path.  This happens when a single
+	//   logical declaration is spread out across multiple places.  The most
+	//   obvious example is the "extend" block again -- there may be multiple
+	//   extend blocks in the same scope, each of which will have the same path.
+	// - A location's span is not always a subset of its parent's span.  For
+	//   example, the "extendee" of an extension declaration appears at the
+	//   beginning of the "extend" block and is shared by all extensions within
+	//   the block.
+	// - Just because a location's span is a subset of some other location's span
+	//   does not mean that it is a descendent.  For example, a "group" defines
+	//   both a type and a field in a single declaration.  Thus, the locations
+	//   corresponding to the type and field and their components will overlap.
+	// - Code which tries to interpret locations should probably be designed to

+	A plugin for the Google protocol buffer compiler to generate Go code.
+	Run it by building this program and putting it in your path with the name
+		protoc-gen-gogo
+	That word 'gogo' at the end becomes part of the option string set for the
+	protocol compiler, so once the protocol compiler (protoc) is installed
+	you can run
+		protoc --gogo_out=output_directory input_directory/file.proto
+	to generate Go bindings for the protocol defined by file.proto.
+	With that input, the output will be written to
+		output_directory/go_package/file.pb.go
+
+	The generated code is documented in the package comment for
+	the library.

+	// whitespace, the same whitespace will be added to every line of the
+	// inserted text.  This is useful for languages like Python, where
+	// indentation matters.  In these languages, the insertion point comment
+	// should be indented the same amount as any inserted code will need to be
+	// in order to work correctly in that context.
+	//
+	// The code generator that generates the initial file and the one which
+	// inserts into it must both run as part of a single invocation of protoc.
