Below is a copy of my email with Francois, clarifying the copy provisions.

You write me:
   
   [...]  Unfortunately I must reject it because of the following
   statement in the doc file:

           I give you the authorization (and will be honored) to distribute
           AZ to everybody you know, but you must not receive money in
           return. AZ must be free.

   Since I do charge a distribution fee for distributing my disks, I cannot
   include this material until this restriction is lifted or until the
   author sends me a written exception to this policy with an explicit
   request that the material be included.  After looking at it, I would
   have included it but for this restriction.

I called the author this morning and that's what he decided:
he does not want to lift the restrictions, because
there are many so-called "PD distributors" in France that charge
scandalous rates for their disks.
However, he gives you explicit authorization for including AZ in
your disk library. (I realize this is not a "written agreement", but
I hope you trust me).
This is, please include in the doc, just after the part you quoted above,
the two following lines:

        Exception: I give the authorization to Fred Fish for including AZ in
        his "Fish disks" library for distribution.
