+#
+# Alright. So, this script goes in your $PATH, and in one of your cron-folders.
+# Personally I prefer /etc/cron.daily, but if you want more than daily
+# precicion on retracting temporary access, you should probably use
+# /etc/cron.hourly (for hourly precicion) or /etc/cron.d.
+#
+# This script uses the environmental variable $RUN_BY_CRON to recognize that it
+# is being run by cron. I set this variable to true in /etc/crontab. You can
+# also symlink this script to your cron-folder, and name the symlink with the
+# suffix "-cron".
+#
 
 # Exit on error. Append "|| true" if you expect an error.
