	  dcron is a time-based job scheduler with anacron-like

	  features.  It works as a background daemon that parses

	  individual crontab files and executes commands on behalf of

	  the users in question.



	  Upon installation, this package will enable a system level

	  cron daemon with hourly, daily, weekly and monthly crontabs.



	  However, it doesn't allow non root users to create their own

	  crontab file. This is because /var/spool/cron/crontabs is

	  non user writable.



	  Typically, a crontab group is created on the system and

	  users allowed to create crontab entries are added into this

	  group, while crontab executable is owned by root:crontab

	  with sgid bit enabled.
