Hello Marc,

Thank you for the reply.

I am still not able to figure out "where is the definition?"

This might be very naive question. This is first time I am working with
proper templated code. So having all sorts of trouble in finding the
definitions.

Can you guide me through one function call? 

In case of /collinear_are_ordered_along_line_2/, 
where would be the implementation? I had a look at
/CGAL/Kernel/interface_macros.h/. It simply defines it as a predicate. Now,
in my case, I am using /Exact_predicates_inexact_constructions_kernel.h/,
which in turn includes /Simple_cartecian.h/. /Simple_cartecian.h/ has
defined the macro. But this does not seem to end.

Where is definition? I mean, at some point one has to do something like:

bool collinear(Point_2& p1, Point_2& p2, Point_2& p3)
{
 return ((      
(p2.x()-p1.x())*(p3.y()-p2.y())-(p3.x()-p2.x())*(p2.y()-p1.y()) )
==  0);
}
in case of collinear() function returning true or false. 

If you think this is a 'common sense' question, please guide me to
respective book/tutorial/man-page.
I appreciate your time investment.

Regards,
S. Gandhi
