+= List Of Tor Implementations =
+
+Useful for interop testing against the specification, diversity of
+the network, studying new approaches and code, running on particular
+platforms, etc.
+
+Experimental, use at your own risk. Some features may be missing.
+
+Due to ongoing change in Tor specification, and experimental nature of new
+code bases, implementations are marked Active / Inactive at one
+year from last commit / release, or upon formal closing. We also try to
+keep the list sorted by activity, but language groupings are more important.
