" The main function: Takes a line of message and generates a reply to it.
The result is a string. If the result is 'noreply, that means: Do NOT reply...
The last field localp is here for historical reasons, and shall be
ignored...
One very important criterion here should be:
erbot should learn to avoid runaway talks with other bots. For this
reason:
[a] it should take a break every now and then, say: a 1-minute break
after every 1000 commands. It should probably announce its break.
AND/OR
[b] It should learn to reply only 99 out of 100 times. Moreover,
before it shuts up, it should let any humans know what it is doing.
tgt, nick and sspec will probably mostly remain unused...
proc == name of the process in the channel
tgt == channel
nick == who from
userninfo looks like (\"deego\" \"user\" \"24-197......\")
sspec looks like: [\"PRIVMSG\"
\"deego!~user@24-197-159-102.charterga.net\" \"#testopn\" \"hi erbot\" \nil

If CHECK is a regexp, it is matched against the user input string. If
it is a match, all the submatches 1....n (NOT 0) are passed to the
function as arguments in that order, except that you can remap using
the optional REMAP list. That list is a list of numbers, like, say (0
