CGAL users discussion list

Hi,

I'm just start to investigate CGAL library and looking for direct access way 
to x/y coordinate container in 2D polygon.

In <CGAL_DIR>/examples/Boolean_set_operations_2/print_utils.h, print_polygon 
give the way to print out x/y coordinate. But it only give in-direct way to 
print out x/y coordinate. Can anyone give a suggestion of direct access way 
to  x/y coordinate container in 2D polygon.
Off-cource, example is very welcome.
