5 # THIS ECLASS IS DEAD: It has been integrated into portage
6 #
7 # Author: Will Woods <wwoods@gentoo.org>
8 #
9 # This eclass is used to automatically update files that typically come with
10 # automake to the newest version available on the system. The most common use
11 # of this is to update config.guess and config.sub when configure dies from
12 # misguessing your canonical system name (CHOST). It can also be used to update
13 # other files that come with automake, e.g. depcomp, mkinstalldirs, etc.
14 #
15 # usage: gnuconfig_update [file1 file2 ...]
16 # if called without arguments, config.guess and config.sub will be updated.
17 # All files in the source tree ($S) with the given name(s) will be replaced
18 # with the newest available versions chosen from the list of locations in
19 # gnuconfig_findnewest(), below.
20 #
21 # gnuconfig_update should generally be called from src_unpack()
