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