Base64 Decoding

[Victor M. J. Ryden]

I'm trying to use python to decode some e-amil I'm getting which
contain MIME base64 encoded documents.

I looked at the doc's for the mimetools and base64 modules. I'm confused
because they ask for both an input AND output file name. I can understand
the input, but not the output. There can be several encoded documents in
a single input file, all of which have their respective file names as part
of the encoding prelude.

Has anyone any experience with this, and do you have any hints?

TIA
