 * An extension to implement a wiki database system.
 * Very much under development, and liable to change.
 * Has external dependencies (e.g. tables need to be
 * created in the wikis database), which I will
 * define once fully known.
 *
 * Full usage instructions can be found on my test wiki,
 * available via the URL defined below ($pWikiDB_URL).
