//! 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.
//!
//! * Compare : Method to compare two vertices.
//!
//! * Compare : Method to compare two edges.
//!
//! * OuterWire : A method to find the outer wire of a
//! face.
//!
//! * Map3DEdges : A method to map all the 3D Edges of
//! a Shape.
//!
//! * Dump : A method to dump a BRep object.
