7 msterret 1.12 # This eclass is used to automatically update files that typically come with
8 wwoods 1.7 # automake to the newest version available on the system. The most common use
9     # of this is to update config.guess and config.sub when configure dies from
10     # misguessing your canonical system name (CHOST). It can also be used to update
11     # other files that come with automake, e.g. depcomp, mkinstalldirs, etc.
12     #
13     # usage: gnuconfig_update [file1 file2 ...]
14     # if called without arguments, config.guess and config.sub will be updated.
15     # All files in the source tree ($S) with the given name(s) will be replaced
16 msterret 1.12 # with the newest available versions chosen from the list of locations in
17 wwoods 1.7 # gnuconfig_findnewest(), below.
