Hi CGAL list,

   Quite some time ago I wrote a few code lines for :
     1. translating an alpha shape to a polyhedron
     2. compute the volume and area of a molecule

Considering my code as helpers or add-ons aside from the CGAL library (not a 
CGAL modification, nor a plain software using the CGAL library), I wondered a 
few seconds what kind of license I should (would be obliged to) use, then 
lazily decided not to bother with it. Now that someone is considering to use 
my code in a scientific project with a resulting software application, these 
questions rise again. 

More specifically my questions are :
  1. Is the development of such CGAL helper code subject to a mandatory type 
of license ? (My code makes use of Alpha shapes 3, HDS and Polyedron3 classes)
  2. More personally, I'd like people to be free to use my code the way they 
want (unspoiled or modified), but I'd like them to acknowledge through a 
citation in the credits or publications. Is there any License type that 
specifies that ?

     Thanks
