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).
