Hi, first attempt the logs stop after 3 hours scanning - not sure why.
the second attempt, the script stoped with a 'segmentation fault' which could mean a lot of things.
I will try to add these to my test suite.
(Probably by getting catalog.sh to read the names out of log files and scan them!)

I plan to have a new release out around the weekend. Scanning should be faster and more accurate too.
