/*
 *  Currently, PUB, DCC and MSG commands are supported.  No party-line
 *      filtering is performed.
 *
 *  For boyfriend/girlfriend support, this module relies on the XTRA
 *      fields in the userfile to use BF and GF, respectively, for
 *      these fields.
 *
 *  userinfo1.0.tcl nicely compliments this script by providing
 *      the necessary commands to facilitate modification of these
 *      fields via DCC and IRC MSG commands.
 *
 *  A basic definition of the parsing syntax follows:
 *
 *      trigger :: seen [ <key> [ [ and | or ] <key> [...]]]
 *
 *        <key> :: <keyword> [ <keyarg> ]
 *
 *    <keyword> :: god | jesus | shit | me | yourself | my | <nick>'s |
 *                 your
 *       <nick> :: (any current on-channel IRC nick or userlist nick or handle)
 *
 *     <keyarg> :: (see below)
 *
 *              KEYWORD KEYARG
 *
 *              my      boyfriend
 *                      bf
 *                      girlfriend
 *                      gf
 *              your    owner
 *                      admin
 *                      (other)
 *              NICK's  boyfriend
 *                      bf
 *                      girlfriend
 *                      gf
