    Changelog for torify changes
    
    Also reinstate the part of the torify script that checks for torsocks
    being installed, so that we can give a more useful message in case it
    isn't.

+  o Removed features:
+
+    - The "torify" script no longer supports the "tsocks" sockifier
+      tool, since it doesn't support DNS and UDP right for Tor.
+      Everyone should be using torsocks instead. Fixes bug 3530 and bug
+      5180. Based on a patch by "ugh".
