 # @DESCRIPTION:
 # This eclass makes trivial X ebuilds possible for apps, drivers,
 # and more. Many things that would normally be done in various functions
 # can be accessed by setting variables instead, such as patching,
 # running eautoreconf, passing options to configure and installing docs.
 #
 # All you need to do in a basic ebuild is inherit this eclass and set
 # DESCRIPTION, KEYWORDS and RDEPEND/DEPEND. If your package is hosted
 # with the other X packages, you don't need to set SRC_URI. Pretty much
 # everything else should be automatic.
