 # Original Apache Group comments on GuessOS

 # Simple OS/Platform guesser. Similar to config.guess but
 # much, much smaller. Since it was developed for use with
 # Apache, it follows under Apache's regular licensing
 # with one specific addition: Any changes or additions
 # to this script should be Emailed to the Apache
 # group (apache@apache.org) in general and to
 # Jim Jagielski (jim@jaguNET.com) in specific.
 #
 # Be as similar to the output of config.guess/config.sub
 # as possible.
