package BRepTools
---Level : Public.
-- All methods of all classes will be public.
---Purpose: The BRepTools package provides utilities for BRep
-- data structures.
--
-- * WireExplorer : A tool to explore the topology of
-- a wire in the order of the edges.
--
-- * ShapeSet : Tools used for dumping, writing and
-- reading.
--
-- * UVBounds : Methods to compute the limits of the
-- boundary of a face, a wire or an edge in the
-- parametric space of a face.
--
-- * Update : Methods to call when a topology has
-- been created to compute all missing data.
--
-- * UpdateFaceUVPoints : Method to update the UV
-- points stored with the edges on a face. This
-- method ensure that connected edges have the same
-- UV point on their common extremity.
