Common Public License (CPL)

[Waldo Bastian]

According to http://www.gnu.org/philosophy/license-list.html#SoftwareLicenses 
the CPL / IPL is incompatible with the GPL. So it would be inappropriate to 
use it in combination with KTTS which is licensed under the GPL. Even though 
there may exists good legal arguments otherwise, KDE prefers to follow the 
interpretation of the GNU project wrt the GPL as much as possible for 
political reasons. For this reason the CPL is unlikely to be added to the KDE 
list of approved license since the purpose of this list is to prevent 
undesired license interaction due to a poor choice of licenses and to put a 
limit on unbound license proliferation within the KDE repository.

Is there any particular reason why these stub libraries can't be licensed 
under a BSD license? Unless IBM is of the opinion that this API deserves 
copyright protection, it seems to me that there are very little protectable 
elements in this stub in the first place.

Cheers,
Waldo
