package ShapeUpgrade 

    	---Purpose:  This package provides tools
    	-- for splitting and converting shapes by some criteria. It
    	-- provides modifications of the kind when one topological
    	-- object can be converted or splitted to several ones. In
    	-- particular this package contains high level API classes which perform: 
    	--      converting geometry of shapes up to given continuity, 
    	--      splitting revolutions by U to segments less than given value, 
    	--      converting to beziers, 
    	--      splitting closed faces.

    --- Purpose: Converts C0 B-Spline curve into sequence of C1 B-Spline curves.
    --           This method splits B-Spline at the knots with multiplicities
    --           equal to degree, i.e. unlike method
    --           GeomConvert::C0BSplineToArrayOfC1BSplineCurve this one does not
    --           use any tolerance and therefore does not change the geometry of
    --           B-Spline.
    --           Returns True if C0 B-Spline was successfully splitted, else
    --           returns False (if BS is C1 B-Spline).
