When the main framework uses GPL covered code, it has to be GPL, too, as far 
as I know, but that doesn't mean that every part of it has to be GPL: 
- http://www.gnu.org/licenses/gpl-faq.html#LinkingWithGPL

Means: Sure you can license every other part under a BSD license (2 clause or 
3 clause), but the whole product will be under the GPL if you use a part 
under the GPL. 

Others can still take just the non-GPL part and use it under the BSD, but as 
soon as a GPL part is in the mix, the whole program becomes GPL. 

If most of a birds body allows you to shoot it down, but its wings disallow 
you to shoot the bird they belong to, then you are not allowed to shoot it. 
If you get the bird to cut off its wings (or if you do it), you can safely 
shoot it and serve it to your landlord for dinner, though. 

That's the reason I almost always use GPL. If you want to shoot a bird, you 
can't use the parts I contributed. But nothing keeps your landlord from just 
enjoying the birds songs of freedom. 

Best wishes, 
Arne
