[Zope-dev] ZPL and GPL licensing issues

[Gregor Hoffleit]

Hmm, I think this discussion doesn't belong to zope-dev.

Still, for those interested in that topic: I raised a similar question on
the debian-legal mailing list just yesterday ("Q: Combining proprietary code
and GPL for in-house use"). The discussion is still ongoing, and it
certainly gives you some insight in the topic:

Just a few points: It looks that from the viewpoint of the FSF, when you're
using the header files of a GPL library, you already have to accept the
license.

I think this is wrong. Providing things on the same media is "mere
aggregation" and therefore not a problem on its own.

It's not acceptable, though, to distribute a proprietary program that has to
be linked with a GPL component by the customer--even if you distribute this
on separate medias!

If you're interested in this, feel free to come over to debian-legal and
read the ongoing discussion.
