7 # This eclass patches ltmain.sh distributed with libtoolized packages with the
8 # relink and portage patch among others
9 #
10 # Note, this eclass does not require libtool as it only applies patches to
11 # generated libtool files. We do not run the libtoolize program because that
12 # requires a regeneration of the main autotool files in order to work properly.
