# @BLURB: Reduces code duplication in the modularized X11 ebuilds.
# @DESCRIPTION:
# This eclass makes trivial X ebuilds possible for apps, fonts, 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.
