<p>Models for the help system.</p>
<p>The database-tied help system is only half of Evennias help
functionality, the other one being the auto-generated command help
that is created on the fly from each commands <strong>__doc__</strong> string. The
persistent database system defined here is intended for all other
forms of help that do not concern commands, like information about the
game world, policy info, rules and similar.</p>
