<p>The help command. The basic idea is that help texts for commands
are best written by those that write the commands - the admins. So
command-help is all auto-loaded and searched from the current command
set. The normal, database-tied help system is used for collaborative
creation of other help topics such as RP help or game-world aides.</p>

<dd><p>Should the specified command appear in the help table?</p>
<p>This method only checks whether a specified command should
appear in the table of topics/commands. The command can be
used by the caller (see the ‘check_show_help’ method) and
the command will still be available, for instance, if a
character type ‘help name of the command’. However, if
you return False, the specified command will not appear in
the table. This is sometimes useful to “hide” commands in
the table, but still access them through the help system.</p>

<p>This command manipulates the help database. A help entry can be created,
appended/merged to and deleted. If you don’t assign a category, the
“General” category will be used. If no lockstring is specified, default
is to let everyone read the help file.</p>
