	Go.xclangspec
	Go language specification for Xcode 3

	This is a preliminary version that supports basic syntax high-lighting
	(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	outdated documentation at: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
	and the files in:
	/Developer/Library/PrivateFrameworks/XcodeEdit.framework/Versions/A/Resources/
