+# @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.
