the Lisp Lesser General Public License



[debian-legal, I was doing audit of ITPs made this year for weird
licenses, or failure to note what license was being used altogether.  I
asked Mr. Rosenberg about #161007.]

Ah.

Okay; there is definitely a virtue in using well-established licenses.

I'm going to raise this license on the debian-legal mailing list just to
get some second opinions on it and otherwise get the -legal list
familiar with it, because I don't recall having seen it mentioned there
before.  (Or maybe I just missed it.)

I am not sure the FSF would agree with Franz Incorporated's
interpretation of how the LGPL would apply to a Lisp module, but on the
other hand the document at the URL does seem to cover that possibility
by claiming to supersede the LGPL in any case where the meanings
conflict.

The LLGPL doesn't look like a problem from a DFSG standpoint to me.  Its
real effect appears to be a liberalization of the copyleft in the LGPL
("Since Lisp only offers one choice, which is to link the Library into
an executable at build time, we declare that, for the purpose applying
the LGPL to the Library, an executable that results from linking a "work
that uses the Library" with the Library is considered a "work that uses
the Library" and is therefore NOT covered by the LGPL.")

debian-legal, what do you guys think?
