+config BR2_PACKAGE_DCRON
+       bool "dcron"
+       depends on BR2_USE_MMU # fork()
+       help
+         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.
