=head1 NAME

remote-notification.pl - Send Weechat notifications to a remote host

=head1 SYNOPSIS

	# in Weechat console, do
	/perl load /path/to/notify.pl

	# or put script in .weechat/perl/autoload/

=head1 DESCRIPTION

remote-notification.pl is a script plugin for Weechat that notifies on common IRC
messages (such as joins, highlights, and private messages) on a *remote* host.

It marshalls the notification in a escaped output to stderr which is
unmarshalled by the terminal application run on the remote host.

By adding the the printer escape codes (ESC[5i (turn printer on) and ESC[4i (turn printer off)
it is possible for terminal to interpret the output by its own script which
then can initiate notify-send or something similar.
The idea is based on L<http://jaredquinn.info/it-related/technical/unix/2007.09.25/libnotify-with-irssi-over-ssh/>.

This script itself is based on the growl-notify script plugin.
