# @ECLASS: libtool.eclass
# @MAINTAINER:
# base-system@gentoo.org
# @BLURB: quickly update bundled libtool code
# @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.

# libtool.eclass, we'll have ECLASSDIR pointing to the active overlay's
# 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.

# Apply a smorgasbord of patches to bundled libtool files. This function

# ${S} will be searched for appropriate files.
#
# If the --shallow option is used, then only ${S}/ltmain.sh will be patched.
#
# The other options should be avoided in general unless you know what's going on.
