+This package provides a data structure to store a two-dimensional
+triangulation that has the  topology of a two-dimensional sphere. 
+The package
+acts as a container for the vertices and faces of the triangulation 
+and provides basic  combinatorial operation on the triangulation.

+\begin{ccPkgDescription}{2D Triangulation}
+\ccPkgSummary{This package  allows to build and handle
+various triangulations for point sets two dimensions.
+Any CGAL triangulation covers the convex hull of its
+vertices. Triangulations are build incrementally 
+and can be modified by insertion  or removal  of vertices. 
+They offer point location facilities.
+
+The package provides plain triangulation (whose faces
+depend on the insertion order of the vertices) and
+Delaunay triangulations.  Regular triangulations are
+also provided for sets of weighted points. Delaunay and regular
+triangulations offer nearest neighbor queries
+and primitives to build the dual Voronoi and power diagrams. 
+
+Finally, constrained and Delaunay contrained triangulations
+allows to force some constrained segments to appear
+as edges of the triangulation. 
+Several versions of constrained and Delaunay contrained triangulations
+are provided: some of them handle intersections between input constraints
+segment while others do not. }
