			==Embargoed documents==

			Automatically remove access restrictions on embargoed documents when the embargo expires.

			For example (where $EPRINTS_ROOT is the root directory of your EPrints install):

			# 01:15 every morning
			15 1 * * * $EPRINTS_ROOT/bin/lift_embargos repository-name

			==Crontab==
			Crontab is the unix command which allows you to execute commands at predetermined times:

			===Creating a crontab===
			The best way to do this is to use "cron" which is an integral part of most UNIX systems.

			To set up cron, run (as the eprints user):

			eprints@host% crontab -e

			You have to add one set of crontab entries per repository.

			The basic crontab syntax is as follows and should be contained in a file.

			* * * * * command to be executed
			- - - - -
			\| \| \| \| \|
			\| \| \| \| +----- day of week (0 - 6) (Sunday=0)
			\| \| \| +------- month (1 - 12)
			\| \| +--------- day of month (1 - 31)
			\| +----------- hour (0 - 23)
			+------------- min (0 - 59)

			==Generate Scripts==
			Outlined in [[Generate Scripts]]. It is advisable to also crontab these scripts to run nightly.

			For example (where $EPRINTS_ROOT is the root directory of your EPrints install):

			# 00:00 every morning at midnight
			0 1 * * * $EPRINTS_ROOT/bin/generate_static repository-name
			# 01:00 every morning at 1am
			0 1 * * * $EPRINTS_ROOT/bin/generate_views repository-name
			# 02:00 every morning at 2am
			0 2 * * * $EPRINTS_ROOT/bin/generate_abstracts repository-name

==Alerts==

To automate sending out these alerts you must add some entries in the crontab (as for views). You need one set of these per archive.

For example (where $EPRINTS_ROOT is the root directory of your EPrints install):

# 00:15 every morning
15 0 * * * $EPRINTS_ROOT/bin/send_alerts repository-name daily
# 00:30 every sunday morning
30 0 * * 0 $EPRINTS_ROOT/bin/send_alerts repository-name weekly
# 00:45 every first of the month
45 0 1 * * $EPRINTS_ROOT/bin/send_alerts repository-name monthly

Note the spacing out so that all 3 don't start at once and hammer the database. You may wish to change the times, but we recommend early morning as the best time to send them (midnight-6am).
