It is scriptable in Perl as a general duplicate file finder.

My initial approach would be to use the 'cksum' command to create a 
checksum string, and stick the pathnames into a hash indexed by 
checksum. When you find a file with a checksum you've already seen, 
you've got a duplicate. There's probably a Perl module that will do a 
checksum so it can all be done within Perl.
