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.
