I have a pair of polygons A & B, and I need to perform boolean 
operations on them to produce the polygon C where C is one of A & B, A | 
B, A|B xor A&B etc. 
If I understand correctly this means I need to use Nef_Polygons of even 
Nef_Polyhedrons and then pull it back out into a complex polygon afterwards.

Can anyone explain the process by which I make that conversion (I keep 
getting compile errors like "unable to convert Point_2 to Extended_point.")

Ideally I'd just create Nef_polygons to start with, store my data in 
them, and be able to perform the boolean operations dirctly on them, but 
that also seems impossible as I need to be able to create them using the 
push_back(point_2) operator or it's equivalent, and I've likewise failed 
to get that to work.

Sorry for what is doubtless a set of noob questions.  This is my first 
real try to do anything with CGAL.

Any help that can be offered will be greatly appreciated.

Thanks,
