=head1 DESCRIPTION

Simple example how to use L<"AHA"> for controlling AVM AHA switches. I.e. 
it is used for using a Lava Lamp as a Nagios Notification handler.

It also tries to check that:

=item watch

The "watch" mode is used for ensuring that the lamp is not switched on for
certain time i.e. during the night. The Variable C<$LAMP_ON_TIME_TABLE> can be
used to customize the time ranges on a weekday basis. 

=item notify

The "notify" mode is used by a notification handler, e.g. from Nagios or from
Jenkins. In this mode, the C<type> parameter is used for signaling whether the
lamp should be switched on ("problem") or off ("recovery").

=item list

This scripts logs all activities in a log file C<$LOG_FILE>. With the "list"
mode, all history entries can be viewed.
