This script tries to list all the cruft on a system with as few as possible false positives to help you keep your system in good working order.
Note that plenty of packages drop extra files all over the place; any extra help is appreciated.
NOTE: This is not the whole script, I got bored updating it in two places so this is just a sample. Follow the below link for the actual script.
