Previously our defaults for DataDirectory, PidFile, RunAsDaemon, and

Log differed from upstreams.  Now Tor behaves just like before (with
our own DataDirectory and all) only when run as the debian-tor user.
If invoked as any other user, Tor will behave just like the pristine
upstream version.

 This is the Debian package for Tor, The Onion Router.

+Some changes have been made to the Tor source to integrate it better into
+Debian.  If Tor is started as the 'debian-tor' user, then:
 
 - RunAsDaemon is enabled by default.
 - PidFile is set to /var/run/tor/tor.pid.  No default upstream.
 - default logging goes to /var/log/tor/log instead of stdout.
 - DataDirectory is set to /var/lib/tor by default.  Uses $HOME/.tor upstream.
 
+If Tor is started as any other user it behaves just like upstream's.
