  31 # This script attempts to guess a canonical system name similar to
  32 # config.sub.  If it succeeds, it prints the system name on stdout, and
  33 # exits with 0.  Otherwise, it exits with 1.
  34 #
  35 # The plan is that this can be called by configure scripts if you
  36 # don't specify an explicit build system type.
