[Typo3] AWstats logfile getting to big

[Arjan Bok]

Hi List
I am using the AWstats extension on a typo3 site hosted by an ISP with 
limited diskspace.
The logfile of AWstats is getting to big (almost 200MB now) which result 
in not being able add anything to the site anymore
Is there an easy way to split the log file in to smaller parts and next 
copy the older parts to a backup somewehere so no log data gets lost?

Thanks, Arjan
