It's meant to allow you to explicitly manage the sys.path[0] value
that gets set implicitly.  That it fits Daniel's use case (as I
understand it) is not coincidental, but it's not meant as a wholesale
substitute for PYTHONPATH.  That would be a separate proposal (which I
believe exists in the tracker already).
