+package BRep 
+
+	---Purpose: This package describes  a Boundary  Representation
+	--          Data   Structure   inherited  from   the  abstract
+	--          Topology   defined  in the   TopoDS  package.  The
+	--          geometric data are provided by the Geom and Geom2d
+	--          packages.
+	--          
+	--          The TVertex,  TEdge,  and TFace  are  redefined in
+	--          this package to add geometric information.
+
+        ---Level : Public  
+        --  All methods of all  classes will be public.

+    --  Edge
+    --
+    --  An Edge is  defined by a list  of curve representations  which
+    --  are either :
+    --  
+    --  Geometric representations :
+    --  
+    --  * A 3d curve (at most one)
+    --  
+    --  * A curve on surface, curve in parametric space.
+    --  
+    --  * A curve on closed surface, two curves in parametric space.
+    --  
+    --  Polygonal representations :
+    --  
+    --  * A 3d polygon (at most one).
+    --  
+    --  * A Polygon on triangulation (array of node indices)
+    --  
+    --  * A Polygon on closed triangulation (2 arrays of node indices)
+    --  
+    --  * A polygon on surface (array of 2d points in parametric space)
+    --  
+    --  Curve on 2 surfaces :
+    --  
+    --  * This is used for storing shape continuity.
