 =head1 DESCRIPTION
 
-This is a wrapper script that allows zoneminder to start and stop itself
-in a manner that keeps it in-sync with systemd.  This script is intended
-to be called internally by zoneminder and may not give the desired results
-if run from the command line.
+This script allows an unpriveledged user to start, stop, or restart the
+zoneminder service on a system running systemd. It does this by redirecting
+commands through pkexec, which checks the available polkit policy files. The
+default policy file grants the system web account user permission. This can be
+changed or expanded by modifying the policy file. See man polkit for details.
