+# A cronjob script to check the current light status (on or off). If the status changes, we
+# send a message to the #dimsumlabs IRC channel via Smuxi.
+#
+# Add this script as crontab entry via "crontab -e" with the same user that smuxi-frontend-gnome is running as:
+# *  * * * * /home/pi/check_light_status_changes.py > /home/pi/check_light_status_changes.out 2>&1
+#
+# For the message sending to to work, it requires Smuxi 1.3 or a git build > May 18th of May 2023 to support --execute-command='/say something'
