DESCRIPTION
       POE::Component::IRC::Plugin::FollowTail is a POE::Component::IRC plugin
       that uses POE::Wheel::FollowTail to follow the end of an ever-growing
       file. It generates "irc_tail_" prefixed events for each new record that
       is appended to its file.

METHODS
   "new"
       Takes two arguments:

       'filename', the name of the file to tail, mandatory;

       'filter', a POE::Filter object to pass to POE::Wheel::FollowTail,
       optional;

       Returns a plugin object suitable for feeding to POE::Component::IRC's
       "plugin_add" method.

OUTPUT
       The plugin generates the following additional POE::Component::IRC
       events:

   "irc_tail_input"
       Emitted for every complete record read. "ARG0" will be the filename,
       "ARG1" the record which was read.

   "irc_tail_error"
       Emitted whenever an error occurs. "ARG0" will be the filename, "ARG1"
       and "ARG2" hold numeric and string values for $!, respectively.

   "irc_tail_reset"
       Emitted every time a file is reset. "ARG0" will be the filename.
