D&D - Dice Roller

=head1 SYNOPSIS

perl irc.pl [options] server room


    Options:
       --help|-h           brief help message
       --port|-p=PORT#     specify the port
       --versions|-v       version information
       --name|n=botname    specify the name of the bot
       --pass|p=password   specify a password

=head1 OPTIONS

=over 8

=item B<--help>

Prints a brief help message and then quits

=item B<--port>

Allows for specifying the port.

=item B<--versions>

Prints out a list of versions for the modules used by the program, and
+ the
program itself.

=item B<--name>

=item B<--pass>

If the server is password protected, set this.

=back

=head1 DESCRIPTION

B<This program> connects to the specified server and joins the request
+ed room.
Once connected, it waits for anyone in that room to say "~xdy+b" each 
+variable
representing the following.

=over 8

=item B<x>

B<x> = the number of dice

=item B<d>

B<d> = a seperator common to D&D and other dice-based games.

=item B<y>

B<y> = the number of sides on the dice

=item B<b>

B<b> = something to arbitraraly add to the sum of the rolls, it is not
+ necessary

=back

This program will then reply to the current chat-room something to the
+ effect
of "E<lt>NAMEE<gt> rolls 4d10+2 and got the following: 4, 6, 10, 9: 31
+"

This program automatically terminates when private messaged the word "
+quit".

=head1 AUTHOR

This program was written by Stephen "Flame" Couchman E<lt>guildms@user
+s.sourceforge.netE<gt>

=head1 COPYRIGHT and REDISTRIBUTION

This program is copyright 2003 Stephen Couchman and may be freely modi
+fied and redistributed under the same terms as Perl itself.

Edit: Some changes made to properly apply the bonus, now only applys to the total rather than to each roll... thought it looked a little funny. Also expanded docs a little more... could still be better documented but for now...
