If you have to ask what's so hard, it's too hard. The OP was about making
the process **SIMPLE**, .. not complicated. Man pages are used to learn
about a command, .. not a way to perform a specific command such as
"change the replicatio0 schedule to start at 8PM instead of 6PM".
Yeah right. That isn't SIMPLE by any definition.
The question was about a way to provide a way to change a crontab entry
for ***NON SYS ADMINS***.
