	einfo
	einfo "2. fcron uses a special binary file format for storing the"

	einfo "   /var/spool/cron/fcrontabs/USERNAME.orig for your reference."
	einfo
	einfo "3. fcron does not feature a system crontab in exactly the"
	einfo "   same way as vixie-cron does. This version of fcron"
	einfo "   features a crontab for a pseudo-user 'systab' for use"

	einfo
	einfo "      fcrontab -u systab /etc/crontab"

	einfo "   Fortunately, it's possible to emulate vixie-cron's behavior"
	einfo "   with regards to /etc/crontab and /etc/cron.d by using a"
	einfo "   little helper script called 'check_system_crontabs'."
	einfo "   The file /etc/fcrontab (not /etc/crontab!) has been set up"

	einfo "   changed since the last generation of the systab and"
	einfo "   regenerate it from those three locations as necessary."
	einfo "   You should run 'check_system_crontabs' once now to properly"

	einfo
	einfo "   The file /etc/fcrontab should only be used to run that"

	einfo "   You may of course adjust the schedule for the script"
	einfo "   'check_system_crontabs' or any other setting in"
