package GeomLProp

    ---Purpose: These global functions compute the degree of
    --          continuity of a 3D curve built by concatenation of two
    --          other curves (or portions of curves) at their junction point.

    ---Purpose: Computes the regularity at the junction between C1 and
    --          C2. The booleans r1 and r2 are true if the curves must
    --          be taken reversed.  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.
