+ASL3_Supermon_Workaround.py by Mason Nelson
+===============================================================================
+This script is a workaround for the Supermon compatibility issue with ASL 3.
+With Asterisk 20 no longer running as the root user, SkywarnPlus is unable to
+write to the old AUTOSKY directories. This script can be added to the crontab
+with root privileges as a workaround to write the alerts to the old AUTOSKY
+directories for Supermon compatibility.
