=head1 NAME

AOL::TOC - Perl extension for interfacing with AOL's AIM service

=head1 SYNOPSIS

  use AOL::TOC;
  $toc = AOL::TOC::new($toc_server, $login_server, $port,
         $screenname, $password);
  $toc->connect();

=head1 DESCRIPTION

This module implements SFLAP, which I presume to be AOL's authenticiation
protocol, and TOC, which is the actual "meat" of the AIM protocol.

=head1 INTERFACE

=head2 connect

connects to the AIM server

=head2 register_callback

This function takes two arguments, the EVENT and the subroutine reference.
Callbacks are similar to the ones found in Net::IRC. The module defines
several AIM "events": ERROR, CLOSED, SIGN_ON, IM_IN, CHAT_IN, UPDATE_BUDDY.
These events can be bound to subroutines.

=head2 dispatch

This flushes all messages to the server, and retreives all current messages.

=head2 add_buddy

Takes one arguement, the nick of the buddy.
This adds a buddy to your buddy list.

=head2 send_im

Takes two arguments, the name of the buddy and the name of the message, and
sends the IM.

=head2 get_info

Takes one argument, the name of the buddy, and returns the info.

=head2 chat_join

Takes one argument, the name of the chat room to join

=head2 chat_send

Takes two arguments, the name of the chat room, and the message.

=head1 AUTHOR

[e-mail] cleaned it up and added DOC
[e-mail] was the original author

=head1 SEE ALSO

Net::AIM, a new module, but it doesn't have the features of this one
