pwebstats & squid common log file

How can I use pwebstats for listing my
proxy access with the squid common log files?

Does anyone have a filter to split the cache.access.log
into cache.log and proxy.log as expected by pwebstats?

Or are there any other solutions?
(at the moment I can't convert to the squid logging format
because I want to analyze some older logs)
