0035 //! The GeomFill package provides two classes to define constrained boundaries:
0036 //! -   GeomFill_SimpleBound to define an unattached boundary
0037 //! -   GeomFill_BoundWithSurf to define a boundary attached to a surface.
0038 //! These objects are used to define the boundaries for a
0039 //! GeomFill_ConstrainedFilling framework.
