Comment:

 Possible bug:  If I have 'tor' and 'tor-gencert' in my path, and I don't
 set the environment variables, won't this fail?

 That is, when you call this code:
 {{{
 +        tor_path = self._env['tor']
 +        if not os.path.exists(tor_path):
 +            print "Cannot find Tor binary: {0}".format(tor_path)
 +            return False
 }}}

 I think that tor_path will be the string "tor", and
 "os.path.exists(tor_path)" will check whether there is a file named "tor"
 in the cwd, but it won't check for whether there is a file named "tor" in
 your path.

 One option is to remove those checks, and to allow subprocess.Popen to
 fail instead.  That won't give such a nice error message, though.
