Purpose:
========
This script allows you to clean up session files (usually used to maintain
a "logged-in session" for http(s) or xmlrpc).

Detailed Instructions:
======================
General syntax: moin [options] maint cleansessions [cleansessions-options]

[options] usually should be:
    --config-dir=/path/to/my/cfg/ --wiki-url=http://wiki.example.org/

[cleansessions-options] see below:
    --name     remove sessions only for user NAME (default: all users)
    --all      remove all sessions (default: remove outdated sessions)
