It works by the assumption that there is _a_ python available as
/usr/bin/env python. This is safe as of Jaguar, unless someone has actually
deleted python. Tough luck for those. The _real_ (python) executable is copied
to Contents/Resources/ and the bootstrapping code calculates its path just like
it calculates the path to the real main script. It passes this path to
os.execve. The bundle can be moved anywhere.
