Library for multipart/form-data encoding in Lua?

[Mariano Kamp <mariano.kamp@...>]

Hi,

  how would one encode form data using "multipart/form-data"? I am  
looking for a library.

  I found some implementations for decoding it, but none for encoding.

  E.g. http://www.google.com/codesearch?q=lang%3Alua+multipart%2Fform-data&hl=en&btnG=Search+Code

  I also looked at lua-socket, but didn't find what I was looking for.

  Any ideas?

Cheers,
Mariano
