Okay, I think I see how this works and it seems reasonable. If the
user wants a distribution, the rule's action copies the source but
doesn't build anything. If the user doesn't ask for a distribution,
then the rule could just forward to the standard exe and lib rules
and build the requested targets.

I wondered how that worked? I found that documentation in my Jamroot
was ignored so I created a Jamfile.v2, put the documentation in there
and mysteriously, bjam picked it up and outputs it before the rest of
the help text.

Anyway, thanks for making that work.
