Small Erlang bencode library

[Steve Smith]

Hi, 

As a preliminary exercise in learning Erlang I've implemented a basic
bencoding library (bencoding being the serialisation system used in the
bittorrent protocol).  The darcs repository is available here:

As this is my first go at declarative programming comments and
corrections are welcome.

Cheers,
Steve
