	=== ~~Ideas for improvement ===~~		=== Running it periodically in the background ====

	*Move the log into /var/log?
	* Find a way to safely allow it ~~to restart~~ the ~~service without asking for a password. (possibly, if it's running from roots crontab...)~~
	* ''<u>'''<span style="color:#c0392b">Then, make it run periodically from cron.</span>'''</u>''
