Apache Log Retention

I enabled apache logs as recomended for the content distribution monitor tool and I have just discovered that the E:\Symantec\Symantec Endpoint Protection Manager\apache\logs folder has grown to 26GB. This is filled with daily error and access log files dating back to June 2012. I have manually deleted some of the files but is there a way to set the retention for these logs so they are automatically deleted?

I am running 12.1 RU1 MP1
