Re: Using LGPLv3+ license for libgnutls?

[Alvaro Lopez Ortega]

Hello Simon,

Relicensing GnuTLS under LGPLv3 could be a problem for some other Free 
Software projects, actually. As you have pointed, it would not be legal 
for GPLv2 software to link against a LGPLv3 library, and that would turn 
to be a major problem for those projects and, at the end of the day, a 
handicap for GnuTLS.

If I looked after GnuTLS' wellbeing, I'd personally stick with the 
current license.  It is a perfectly fine Free Software license that 
wouldn't decrease GnuTLS' potential target audience.

Besides, it would be definitely much more friendly with the Free 
Software developers who either don't follow the GPLv3 way or they are 
not ready yet to do so.
