Comment(by rransom):

 Replying to [comment:1 mikeperry]:
 > I dunno. I designed TOR_TRANSPROXY in #6254 so that a command line user
 could easily override the use of Vidalia+Tor...

 I think that most users do not understand environment variables (based on
 the fact that some ''developers'' of Tor products have not understood them
 in the recent past).  I think that users who do understand environment
 variables can edit the script (or write a replacement from scratch)
 themselves, and users who do not understand them should use canned scripts
 prepared (or at least reviewed) by people who do understand them.

 > I actually think our startup script should be more friendly for people
 who want to create wrappers for alternate launch modes for things like
 Tails or for use with a system tor instance.

 If a user unintentionally runs TBB with the `TOR_TRANSPROXY` environment
 variable set, they have lost their anonymity completely.  If Tails or some
 other product which configures TorBrowser to use a system Tor cannot pass
 the `TOR_TRANSPROXY` environment variable through the `start-tor-browser`
 script, they will have to ship their own script -- which they would have
 to do anyway in order to launch the browser without an extraneous instance
 of Vidalia.
