+# @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.
