 When I set my torrc to say
 {{{
 ClientTransportPlugin obfs2 exec /path/to/nonexistent/file --managed
 }}}

 then the way Tor tells me it couldn't launch or find the file is by
 logging
 {{{
 Feb 10 03:23:28.000 [warn] Could not launch managed proxy executable!
 Feb 10 03:23:28.000 [warn] You have a Bridge line using the obfs2
 pluggable transport, but there doesn't seem to be a corresponding
 ClientTransportPlugin line.
 }}}

 That second line is confusing people. It's not true.

 If I then change the line to
 {{{
 ClientTransportPlugin obfs2 exec /bin/false --managed
 }}}
 I get
 {{{
 Feb 10 03:29:57.000 [notice] Managed proxy stream closed. Most probably
 application stopped running
 Feb 10 03:29:57.000 [notice] Failed to terminate process with PID '13672'
 Feb 10 03:29:57.000 [warn] You have a Bridge line using the obfs2
 pluggable transport, but there doesn't seem to be a corresponding
 ClientTransportPlugin line.
 Feb 10 03:29:58.000 [notice] Bootstrapped 5%: Connecting to directory
 server.
 Feb 10 03:29:58.000 [warn] Tried to connect through proxy, but proxy
 address could not be found.
 }}}

 Again the warn line is what people look to. Also, should the "it closed"
 be a warn in this case? Also also, what's with the "tried to connect
 through proxy" line -- why does it tell me the proxy address could not be
 found?
