for research purposes I'd like to implement my modified version of the Tor source code in the Shadow simulation network, but I am not exactly sure how to do that. Shadow uses a plug-in called Scallion that is a wrapper for the Tor source code. This solved question (http://tor.stackexchange.com/questions/1755/how-to-implement-the-modified-source-code-of-tor) merely mentions the idea, but could someone please explain to me clearly the steps of doing modifications in Shadow?
Thanks!
