crontab is indeed very like UNIX' crontab, so you can schedule repeated
jobs. But of course it is programmed in java, so you could programmaticly
add and remove jobs, which probably means that a task can also itself
schedule or remove tasks.

Actually, another differnce may be that the granularity of crontab is only a
minute, so you can't run anything more often than that (it would be a rather
straightforward extension on the crontab syntax to fix that, but it is a bit
more tricky to implement).
