# on your wiki. After this script is run, we suggest to:
#
#    1. Register the superuser. For example:
#	Login > UserPreferences > Create Profile
#    2. Create a EditGroup page.
#    3. Add registered user names into EditGroup page.
#
#       At this point those users listed in EditGroup will
#       be able to edit pages on your wiki. If you need to
#       grant admin rights to other people then create the
#       AdminGroup page and add register users names into
#       it. After that they will have admin rights.

#       More info about acl can be found at
#       http://localhost/wiki/HelpOnAccessControlLists once

    MoinMoin - Configuration for a single wiki

    If you run a single wiki only, you can omit the farmconfig.py config
    file and just use wikiconfig.py - it will be used for every request
    we get in that case.

    Note that there are more config options than you'll find in
    the version of this file that is installed by default; see
    the module MoinMoin.multiconfig for a full list of names and their
    default values.

    Also, the URL http://moinmoin.wikiwikiweb.de/HelpOnConfiguration has
    a list of config options.

    ** Please do not use this file for a wiki farm. Use the sample file 
    from the wikifarm directory instead! **

    # Critical setup  ---------------------------------------------------

    # Misconfiguration here will render your wiki unusable. Check that
