Gnustep and frameworks

[andy.somogyi]

Hello

Are the Mac / NextStep style frameworks (a directory with a shared  
lib and header files) supported in Gnustep / Linux?

Is there support for using them via the gcc -framework option and for  
creating them via the gnustep make?

Reason why I ask is that:
a: I think frameworks are a VERY nice way of creating and using  
shared libs.
b: We are working on a number of applications on the Mac side and we  
want them to be portable to Gnustep / Linux,
   and these make heavy use of shared frameworks.

thanks
