# @DESCRIPTION:

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

# eclass/ dir, but libtool.eclass is still in the main Gentoo tree. So
|
|
# add a check to locate the ELT-patches/ regardless of what's going on.
