OK, folks, here's a heads up on the issue of license for the Calendrical
Calculation code. The "commercial" statement below is not encouraging,
but I'm sending  him the licenses, and hoping for the best. If someone
wants to step in and give me good advocacy words to use when I get his
response, I'd be delighted to ghostwrite them.

I am not familiar with the license; please do send it.  We would want to
restrict any commercial (for profit) use.

What we did with the Java and Mathematica translations was agree that the
translator would have non-transferable rights to use the code commercially in
exchange for our receiving ownership of the translations (with the right to
distribute it).

It would be advantageous from our pint of view to have the Perl version, so
we'd be happy to make similar arrangements.  We do expect that the Perl
translation would be a full translation of all the Lisp code, not just
selections from it.
