<!--
	GtkSourceView syntax highlight for Gentoo-specific files

	Originally written for gtksourceview-1.x by:
		Leonardo Ferreira Fontenelle <leo.fontenelle@gmail.com>, 2006.
	Rewritten for gtksourceview-2 by:
		Rene 'Necoro' Neumann <necoro@necoro.net>, 2007
	
	Distributed under the same license(s) as gtksourceview.

	TODO:
	- do not highlight "enable" in the configure options
	- perhaps highlight portage variables and portage functions different
