    ---Purpose: These global functions compute the degree of
-- continuity of a curve built by concatenation of two
-- edges at their junction point.

    ---Purpose: Computes the regularity at the junction between C1 and
    --          C2. The point u1 on C1 and the point u2 on  C2 must be
    --          confused.   tl  and ta  are  the  linear  and  angular
    --          tolerance used two compare the derivative.

    ---Purpose: The  same  as  preciding   but   using  the   standard
    --          tolerances from package Precision.
    returns Shape from GeomAbs;
