5     # @ECLASS: libtool.eclass
6     # @MAINTAINER:
7     # base-system@gentoo.org
8     # @BLURB: quickly update bundled libtool code
9     # @DESCRIPTION:
10 azarah 1.1 # This eclass patches ltmain.sh distributed with libtoolized packages with the
11 azarah 1.24 # relink and portage patch among others
12 vapier 1.75 #
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.
16 rac 1.34
17 vapier 1.96 # If an overlay has eclass overrides, but doesn't actually override the
18     # libtool.eclass, we'll have ECLASSDIR pointing to the active overlay's
19     # eclass/ dir, but libtool.eclass is still in the main Gentoo tree. So
20     # add a check to locate the ELT-patches/ regardless of what's going on.
