Attempting to get Obfsproxy3 to work.

With Tor v0.2.4.11-alpha and Obfsproxy pulled from https://git.torproject.org/obfsproxy.git yesterday this is what I get at runtime:

Apr 05 14:57:23.000 [warn] Server managed proxy encountered a method error. (obfs3 could not setup protocol) Apr 05 14:57:23.000 [warn] Managed proxy at '/usr/bin/obfsproxy' failed the configuration protocol and will be destroyed

I have no problems with obfs2, but obfs3 success continues to elude me.

That obfsproxy.git still contains the old obfsproxy written in C that does not (yet) have obfs3 support -- and maybe never will.

The new obfsproxy is written in Python and has obfs3 support. It was called "pyobfsproxy" for quite some time to discriminate the two. It was decided that it would confuse people less if there was just "a new release of obfsproxy, now written in Python". It sounds like a simple rename, but the transition involves a lot of steps. That's also the reason why the current available instructions are "outdated": We are sitting on newer instructions that work with pyobfsproxy, but since pyobfsproxy is not yet available under the name obfsproxy, the instructions are not published on the website yet.
