I installed it, run it simply on my test cases and got a coverage report, wow, that was simple. Actually it wasn't that simple. The test cases are in different files, so just had a file called runthetest.pl that did require $ARGV;. But it was still simple. My simple test cases for this project showed a 90% coverage, I was in shock, I had thought 50% or so, (351 out of 3412 lines untested).
Now I just need to find away to do coverage analysis of the C parts for threads
