   Or you could frob bash's she-bang parsing.

Easier to frob exec.  Then all shells that do hash-bangs will follow.

Make exec strip the leading directory, and then you have something
like `#!foo', which exec is already nice enough to handle for us.  It
will look through PATH for `foo', and run it if it was found.

Not sure if this is ugly or not... Or if it will break things...
