Cron on solaris do not take the same
set of option than vixie cron on linux, and
among the biggest difference, root cannot set
the crontab of a user directly from a file. Thus the
use of su to run the crontab command. Fix issue #4648
Bugs:
(1) no longer allow empty jobs
(2) strip the header added by crontab package used in openSuSE and SuSE
(3) try not to leak temp files when things go wrong
(4) issue returning job names under certain conditions
Enhancements:
(1) Allow all special times not just reboot.
(2) Fail earlier by performing more input validation
(3) Add feature to allow removing cron file under /etc/cron.d
ToDo:
(1) Validate times (minute, hour, ...)
(2) Strip white space from fields such as name and job such that name=foo equals name=' foo'.
(3) More testing
Migrated all examples: in DOCUMENTATION=''' string to standalone EXAMPLES=''' string
Added deprecation warning to moduledev.rst and remove deprecated example from it
Fixed up a few typos and uppercased some acronyms.
