It requires you to export your logs into text format, either with Smartview Tracker (which seems to take forever) or with 'fwm logexport' (there's a script included if you want to modify it). All code is provided as is, drop me a comment if you find any use for it!
I don't have any formal instructions but the comments should be enough to get you though. It's all Python 2.6 but should work in 2.7. Not tested in 3.x. When you've got the code downloaded, run analyse.py and point the script to your rulebases_5.0.fws and text log file. It will churn through the log file and should spit out an HTML file showing which logs are hit, how many times and which are never hit. It's not perfect, but it's a good starting point for clearing out a rulebase.
Analyse.py : Run this and follow prompts
fwlog2txt.sh : This will dump logs in a particular range to a big text file to use with the tool. To be run on your gateway / Smartcenter
logFunc.py : The modules and routines called by analyse.py
style.css : Not essential, but makes the html output a little prettier
