# config.sub.  If it succeeds, it prints the system name on stdout, and
# exits with 0.  Otherwise, it 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
