# @BLURB: Refresh bundled gnuconfig files (config.guess, config.sub)
# @DESCRIPTION:
# This eclass is used to automatically update files that typically come with
# automake to the newest version available on the system. The most common use
# of this is to update config.guess and config.sub when configure dies from
# misguessing your canonical system name (CHOST). It can also be used to update
# other files that come with automake, e.g. depcomp, mkinstalldirs, etc.
#
# usage: gnuconfig_update [file1 file2 ...]
