Torrent Pieces Hash Verification: Compare downloaded data with torrent data

This package can be used both on Linux/Windows (or any other platform which php supports) in order to compare
the hashes from a torrent metadata file with an actual torrent data directory and produce a report of which files
/pieces should be re-downloaded and how much data that is (in mb). if for example you have downloaded a torrent's
file data (not the .torrent file but the actual data) and the torrent file is for some reason updated or changed
you can use this utility to compare the new .torrent file with the data you have already downloaded and see what
needs to be downloaded and what size that is.

The script takes two required arguments and one optional:

compare_hash.php <torrent_file> <path> [output_file]

[required] torrent_file: The torrent file from which to read hashes
[required] path: The path of the torrent data
[optional] output_file: If specified the output will be saved to that file instead of console (stdout).

Used packages:

BDecode from Andrew Chaus (http://www.phpclasses.org/browse/package/3473.html)
File_Bittorrent2 (some methods only) from Markus Tacker, Justin Jones (http://pear.php.net/package/File_Bittorrent2)
