+=head1 NAME
+
+notifyquit.pl
+
+=head1 DESCRIPTION
+
+A script intended to alert people to the fact that their conversation partners
+have quit or left the channel, especially useful in high-traffic channels, or
+where you have C<JOINS PARTS QUITS> ignored.
+
+=head1 INSTALLATION
+
+This script requires that you have first installed and loaded F<uberprompt.pl>
+
+Uberprompt can be downloaded from:
+
+L<https://github.com/shabble/irssi-scripts/raw/master/prompt_info/uberprompt.pl>
+
+and follow the instructions at the top of that file or its README for installation.
+
+If uberprompt.pl is available, but not loaded, this script will make one
+attempt to load it before giving up. This eliminates the need to precisely
+arrange the startup order of your scripts.
+
+Copy into your F<~/.irssi/scripts/> directory and load with
+C</SCRIPT LOAD F<notifyquit.pl>>.
+
+=head1 SETUP
+
+This script provides a single setting:
+
+C</SET notifyquit_exceptions>, which defaults to "C</^https?/ /^ftp/>"
+
+The setting is a space-separated list of regular expressions in the format
+C</EXPR/>. If the extracted nickname matches any of these patterns, it isa
+assumed to be a false-positive match, and is sent to the channel with no
+further confirmation.
+
+=head1 USAGE
+
+When responding to users in a channel in the format C<$theirnick: some message>
+(where the C<:> is not necessarily a colon, but the value of your
+C<completion_char> setting), this script will check that the nickname still
+exists in the channel, and will prompt you for confirmation if they have
+since left.
+
+It is intended for use for people who ignore C<JOINS PARTS QUITS>, etc, and
+try to respond to impatient people, or those with a bad connection.
+
+To send the message once prompted, either hit C<enter>, or C<y>. Pressing C<n>
+will abort sending, but leave the message in your input buffer just in case
+you want to keep it.
