@ -46,9 +46,12 @@ There are three versions of constrained triangulations
<LI>In the basic version, the constrained triangulation
does not handle intersecting constraints, and the set of input
constraints is required to be a set of polylines that do not intersect
except possibly at their endpoints. Any number of constrained edges
may share the same endpoint. Constrained edges may be vertical or
have zero length.

An exception of type `Intersection_of_constraints_exception`
is thrown upon insertion of a constraint intersecting in
its interior an already inserted constraint.

<LI>The two other versions support intersecting input constraints.
In those versions, input constraints may consist of
intersecting, overlapping or partially
