   3 # server-version.py: print a Subversion server's version number
   4 #
   5 # USAGE: server-version.py URL
   6 #
   7 # The URL can contain any path on the server, as we are simply looking
   8 # for Apache's response to OPTIONS, and its Server: header.
   9 #
  10 # EXAMPLE:
  11 #
  12 #   $ ./server-version.py http://svn.collab.net/
  13 #                   or
  14 #   $ ./server-version.py https://svn.collab.net/
  15 #
  16 # Python 1.5.2 or later is required.
