On reflection, it seems a pretty poor solution, so I'll reopen this as
a wishlist.

Summary:

When using --script, it would be nice if there was a simple way for
the file so loaded to identify itself as the "main file", distinct
from any libraries it might require.


(I'd probably just use a hack like:

#!/bin/sh

exec emacs -batch -l test.el -f batch-run-test

but I suppose this is against the spirit of --script)
