7 | # This eclass is used to automatically update files that typically come with |
| 8 | # configure dies from misguessing your canonical system name (CHOST). |
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. |
