13# much, much smaller. Since it was developed for use with
14# Apache, it follows under Apache's regular licensing

16# to this script should be Emailed to the Apache
17# group (apache@apache.org) in general and to
18# Jim Jagielski (jim@jaguNET.com) in specific.
19#
20# Be as similar to the output of config.guess/config.sub
