# Configuration of MoinMoin under Apache.
#   * You can run this to do your initial configuration, or just to add
#     a new instance.  
#   * You better be root when you run this.
#   * Creates:
#     - http://your-server/$MOININSTANCE (CGI access to your wiki)
#     - http://your-server/mod-$MOININSTANCE (mod_python access via wrapper)
#     - http://your-server/newmod-$MOININSTANCE (mod_python access w/o wrapper)
#
# Customize these to suit your site:
#   MOININSTANCE	the name you want given to your new instance.
#   MOINSHARE		where did setup.py put your moin shared files?
#   MOINWIKIS		the directory that will contain all of your wiki instances
#   APACHEDIR		the name of the directory that *contains* your apache conf directory.
#   PYSITE		the path name of your python site-packages dir.
