package Geom2dGcc
--- Purpose: The Geom2dGcc package describes qualified 2D
-- curves used in the construction of constrained geometric
-- objects by an algorithm provided by the Geom2dGcc package.
-- A qualified 2D curve is a curve with a qualifier which
-- specifies whether the solution of a construction
-- algorithm using the qualified curve (as an argument):
-- - encloses the curve, or
-- - is enclosed by the curve, or
-- - is built so that both the curve and this solution are external to one another, or
-- - is undefined (all solutions apply).
-- These package methods provide simpler functions to construct a qualified curve.
-- Note: the interior of a curve is defined as the left-hand
-- side of the curve in relation to its orientation.

-- Warning
-- Obj is an adapted curve, i.e. an object which is an interface between:
-- - the services provided by a 2D curve from the package Geom2d,
-- - and those required on the curve by a computation algorithm.
-- The adapted curve is created in the following way:
-- Handle(Geom2d_Curve) mycurve = ...
-- ;
-- Geom2dAdaptor_Curve Obj ( mycurve )
-- ;
-- The qualified curve is then constructed with this object:
-- Geom2dGcc_QualifiedCurve
-- myQCurve = Geom2dGcc::Unqualified(Obj);

---Purpose: Constructs such a qualified curve that the solution
-- computed by a construction algorithm using the qualified
-- curve encloses the curve.
