  10 # @BLURB: Reduces code duplication in the modularized X11 ebuilds.
  11 # @DESCRIPTION:
  12 # This eclass makes trivial X ebuilds possible for apps, fonts, drivers,
  13 # and more. Many things that would normally be done in various functions
  14 # can be accessed by setting variables instead, such as patching,
  15 # running eautoreconf, passing options to configure and installing docs.
  16 #
  17 # All you need to do in a basic ebuild is inherit this eclass and set
  18 # DESCRIPTION, KEYWORDS and RDEPEND/DEPEND. If your package is hosted
  19 # with the other X packages, you don't need to set SRC_URI. Pretty much
  20 # everything else should be automatic.
