Examples ought indeed to be in the final documentation.

Note that with ABL, you must carefully load ABL and set whichever
variable in each Lisp startup script, so the amount of work is no
less.

I suppose you could use logical pathnames on the destination side of
your translations.
Configuring logical pathnames is out of the scope of AOL. But the docs
should suggest the idea.
logical pathnames are also a cthulhuesque piece of non-portability horror.

That's tricky. How do you currently do that with ABL?

Certainly.
