[OT] Finding a Torrent file editor

[grarpamp]

Anyone know of a torrent file editor?

All I need to do is:

- Strip out all the former random and old meta info crap people put
in their torrents and replace it with a set of trackers keeping the
hashed info the same. A comment field would be nice. Other fields
would be a bonus.

- Similarly, create new torrent files from new file hierarchies.

- Print the infohash.

- Open source

- Must be 100% scriptable from the command line, regardless of
whether or not there is an interactive or gui mode.

So yeah, a torrent file editor and creator.

Not having much luck searching with all the torrent and windows
craze on the net. And I'm not seeing anything in ports so far.

Any ideas? Thanks.
