Stop anacron?

[Bob Goodwin]

How can I stop anacron from running if cron has already run just before?

Or if they would each save to different log files I guess that would 
work too.

As it is if the computer is running at four in the morning both are 
saved to a file that is sent to me and I wind up reading through 
essentially the same set of data twice.  A minor thing I suppose but I 
would prefer getting it only once.
