# This eclass is used to automatically update files that typically come with |
| 8 |
# 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 |
# with the newest available versions chosen from the list of locations in |
| 17 |
# gnuconfig_findnewest(), below. |
