Obfsproxy is a pluggable transport proxy written in Python. See doc/HOWTO.txt for installation instructions. If you want to write a pluggable transport, see the code of already existing transports in obfsproxy/transports/ . Unfortunately a coding guide for pluggable transport authors does not exist at the moment!
