The code

Funny thing about this program
The first executable code is at line 265
It's 907 lines long, of which 513 lines (57%) are comments
- That's a record
- The author has made extensive notes, to-do lists, etc
- All in the program's comments
Typical excerpt:

        #  pass 2: compare all files to each other
        #  There's probably a name for this algorithm:
        #
        # ex: files a, b, c, d, e
        # if none match, the following files are compared
        #       (a,b) (a,c) (a,d) (a,e)
        #       (b,c) (b,d) (b,e)
        #       (c,d) (c,e)
        #       (d,e)
        # BUT if any match, delete them from the list
        #
        # ex: in the list (a,b,c,d,e), files a, c, e are all identical
        # so in the first pass, (a,c) and (a,e) comparisons succeed
        # leaving the file list as b, d
        # since there's no need to further compare files that matched!
        #
        # Oh yea, and save all the successes as an array of arrays.
