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