   Not everyone here knows what `exec -a` is so let me say that it's a
bashism that sets program's name. `exec prog` is interpreted as a system
call `exec('prog', 'prog')` and  `exec -a name prog` is interpreted as
`exec('prog', 'name')`.

   Currently sys.argv[0] is the name of the script and it should stay
that way. But it would be interesting to preserve argv[0] from C and
expose it via sys in addition to sys.executable. Something like
sys.original_prog_name. Then the OP can do anything application-specific
-- set sys.argv[0], call setproctitle, whatever.

           Programmers don't die, they just GOSUB without RETURN.
