+	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
