Could use a regexp function on lines to trigger.  I feel regexp is too
complex for something as simple as that though.

Lemme see if I can get this right, DartMUD:

 * Break the sentance down into more strings (ie: fullstops, exclamation
   marks, etc, maybe commas).

 * Take first word and see if it is a verb stored in the hash tables.

 * If not, discard, repeat with second word, etc

 * If there's a match, grab the rules related to the verb and try and fit
   the rest of the sentance into the rule.  So give would have the rule:


   Or sell would have:

      VERB BEING OBJECT  (eg: sell me your finest sword)
      VERB OBJECT        (eg: sell sword)

   Getting a bit muddled here (I'm in between fixing ultrasonics).

 * Also, there is a hash table of all the objects and a hash table of
   all the descriptions.  So sword is pretty obvious, 'finest' would
   be translated to best sword (either ornate, expensive, or lethal).

Um, that didn't make sense to me either.  Anyway, it doubles up as a
command parsing solution.  It's quite cute coz you can add stuff like 'hi'
for a verb.  Hmm, how about, instead of directly controlling the
character, players sort of talk to the characters and tell them what to

'K, not that chatty, how about:

Back to some DSPs.  Ciao
