	go.xclangspec
	Go language specification for Xcode 4.x.

	This is a preliminary version that supports basic syntax coloring
	(such as keywords, literals, and comments) and an attempt to provide
	some structure information (incomplete).

	There is not much documentation available regarding the format
	of .xclangspec files. As a starting point, see for instance the
	outdated documentation at:

		http://maxao.free.fr/xcode-plugin-interface/specifications.html
