Try this:

PYTHONPATH=whatever exec /path/to/python $0 ${1+"$@"}

The trick here is that Python sees those three lines as a triple-quoted 
docstring, but the shell sees the first line as a no-op, and then bails out 
after the 'exec', so it doesn't read the rest of the file.  The ${} magic 
is shell quoting stuff to make sure that all arguments are properly 
escaped; I don't pretend to understand how it works.  :)
