Reduce / Delete Web logs and Stats logs

[cfuze]

I have searched but I am not finding exactly what I think I need. I need to be able to delete the stats logs and any other logs that could be taking up space. Right now, it appears I have GB's of logs. In the Stats admin panel, most of the sites have 1.3 GB of logs per month and in total, it appears to be quite large. Does ISPC auto-prune these? If so when and can I do it more often? If not, is it possible to do via a cron? If so, any help in this direction?

Thanks!
