       with nickname and channel tracking

SYNOPSIS

        # A simple Rot13 'encryption' bot

DESCRIPTION

       POE::Component::IRC::Qnet::State is an extension to POE::Component::IRC::Qnet specifically
       for use on Quakenet <http://www.quakenet.org/>, which includes the nickname and channel
       tracking from POE::Component::IRC::State. See the documentation for
       POE::Component::IRC::Qnet and POE::Component::IRC::State for general usage.  This document
       covers the extensions.

METHODS

       "ban_mask"
           Expects a channel and a ban mask, as passed to MODE +b-b. Returns a list of nicks on
           that channel that match the specified ban mask or an empty list if the channel doesn't
           exist in the state or there are no matches. Follows Quakenet ircd rules for matching
           authed users.

       "is_nick_authed"
           Expects a nickname as parameter. Will return that users authname (account) if that
           nick is in the state  and have authed with Q. Returns a false value if the user is not
           authed or the nick doesn't exist in the state.

       "find_auth_nicks"
           Expects an authname and a channel name. Will return a list of nicks on the given
           channel that have authed with the given authname.

       "nick_info"
           Expects a nickname. Returns a hashref containing similar information to that returned
           by WHOIS. Returns a false value if the nickname doesn't exist in the state. The
           hashref contains the following keys: 'Nick', 'User', 'Host', 'Server', 'Auth', if
           authed, and, if applicable, 'IRCop'.

INPUT

       These additional events are accepted:

       "resync_chan"
           Accepts a list of channels, will resynchronise each of those channels as if they have
           been joined for the first time. Expect to see an "irc_chan_sync" event for each
           channel given.

       "resync_nick"
           Accepts a nickname and a list of channels. Will resynchronise the given nickname and
           issue an "irc_nick_sync" event for each of the given channels (assuming that nick is
           on each of those channels).

OUTPUT EVENTS

       This module returns one additional event over and above the usual events:

       "irc_nick_authed"
           Sent when the component detects that a user has authed with Q. Due to the mechanics of
           Quakenet you will usually only receive this if an unauthed user joins a channel, then
           at some later point auths with Q. The component 'detects' the auth by seeing if Q
           decides to +v or +o the user. Klunky? Indeed. But it is the only way to do it,
           unfortunately.

       The following two "irc_*" events are the same as their POE::Component::IRC::State
       counterparts, with the additional parameters:

       "irc_quit"
           "ARG3" contains the quitting clients auth name if applicable.

       "irc_part"
           "ARG3" contains the parting clients auth name if applicable.

       "irc_kick"
           "ARG5" contains the kick victim's auth name if applicable.

CAVEATS

       Like POE::Component::IRC::State this component registers itself for a number of events.
       The main difference with POE::Component::IRC::State is that it uses an extended form of
       'WHO' supported by the Quakenet ircd, asuka. This WHO returns a different numeric reply
       than the original WHO, namely, "irc_354". Also, due to the way Quakenet is configured all
       users will appear to be on the server '*.quakenet.org'.

BUGS

       A few have turned up in the past and they are sure to again. Please use
