  27 # This script attempts to guess a canonical system name similar to
  28 # config.sub.  If it succeeds, it prints the system name on stdout, and
  29 # exits with 0.  Otherwise, it exits with 1.
  30 #
  31 # The plan is that this can be called by configure scripts if you
  32 # don't specify an explicit system type (host/target name).
  33 #
  34 # Only a few systems have been added to this list; please add others
  35 # (but try to keep the structure clean).
