Ftp client

hi , can any one help me with this one:

I need a source code of a light ftp (C or C++) client (at most 100K of weight after compilation , better even less then ~50K).
The requiremenst are that it won't use any external libreries like STL (will use only sockets).
It shouldn't implement all of ftp funcitons , all i need is only upload and download of files (no directory listing / creating ect...)

I would really appriciate if you have any written source / idias or references that can help.

Thanks ALOT!
