Libraries for multipart MIME encoding/decoding?

[Tom Moertel]

Before I rush off and reinvent another wheel, does anybody know of a
Haskell library to perform MIME encoding and decoding (a la IETF RFC
2045)?  I'd like to be able to decode and process binary files submitted
via HTTP POST, and so I need multipart support.  The CGI libraries
listed on www.haskell.org don't seem to offer this, hence my request.

Thanks for any pointers or advice you may be able to provide.

Cheers,
Tom
