+#
+# This eclass is designed to reduce code duplication in the modularized X11
+# ebuilds.
+#
+# Using this eclass:
+#
+# Inherit it. If you need to run autoreconf for any reason (e.g., your patches
+# apply to the autotools files rather than configure), set SNAPSHOT="yes". Set
+# CONFIGURE_OPTIONS to everything you want to pass to the configure script.
+#
+# If you have any patches to apply, set PATCHES to their locations and epatch
+# will apply them. It also handles epatch-style bulk patches, if you know how to
+# use them and set the correct variables. If you don't, read eutils.eclass.
+#
+# If you're creating a font package and the suffix of PN is not equal to the
+# subdirectory of /usr/share/fonts/ it should install into, set FONT_DIR to that
+# directory or directories.
+#
+# IMPORTANT: Both SNAPSHOT and FONT_DIR must be set _before_ the inherit.
+#
+# Pretty much everything else should be automatic.
