I was initially worried about leaving stale files / handles around. But if
the copies get removed, the links would too.

So I am tentatively with Kevin: maybe it is time to update the helper install
script.

But I (as a non-Elisp programmer) would not more help than the casual two
bits of 'replace foo with bar' he tossed my way.

Kevin:  a patch would be good, or at least another example package you
recommend I follow.
