-# makeedit eclass, will remove -Wreturn-type and -Wall from compiling,
-# this will reduce the RAM requirements.
+# To use this eclass, do 2 things:
+#   1. append-flags "$MAKEEDIT_FLAGS".  If you filter-flags, make sure to do
+#      the append-flags afterward, otherwise you'll lose them.
+#   2. after running configure or econf, call edit_makefiles to remove
+#      extraneous CFLAGS from your Makefiles.
+#
+# This combination should reduce the RAM requirements of your build, and maybe
+# even speed it up a bit.
