APPLEJACK
This is a shell script for cleaning up the mess left by system crashes: disk directory errors, buggy caches, corrupted preferences, etc

All you do is run the SimpleInstaller. Reboot into single user mode, and follow the other instructions.

This has a very computer look and feel and it has a little more feedback than that of the other OS X utilities of the like. (Onyx - Cocktail)
