CGAL users discussion list

Hi,all

I am using the segment_delaunay_graph demo, 
(http://www.cgal.org/Manual/3.3/doc_html/cgal_manual/packages.html#part_IX). 
If I want to get the (coordinates of) vertices and edges of the voronoi 
diagram, I need to know how the output data file *.hsdg are organized. But I 
can't find any instruction either from the demo or the CGAL website.

Any advice and reply is highly appreciated and anticipated.
