[Help-gnutls] Re: Using LGPLv3+ license for libgnutls?

[Simon Josefsson]

The license compatibility matrix is useful, see:

http://www.gnu.org/licenses/gpl-faq.html#AllCompatibility

The problem is for GPLv2-only projects that wants to use a LGPLv3
library.

Using LGPLv3+ also has consequences for projects that wants to copy code
from GnuTLS (they need to be GPLv3+ or LGPLv3+), but that is not
something that happens widely enough to care about as far as I am aware.
If anyone knows of significant code re-use from gnutls, let me know.
