Release Notes: Added SHA1 algoritm. Removed need for md5sum binary, but now requires Digest::SHA1 and Digest::MD5 from CPAN to function properly.
Release Notes: Added -r (rename) and -rdir (rename dir) command line options.
Release Notes: Directory traversal of the download directory.
Release Notes: whatpix now uses getopt, only shows new duplicates (with option to automatically delete them), and can now optionally use an alternate md5sum path.
