Tol : Real from Standard;
E : Curve from Geom2dAdaptor) -- en fait in out
---Purpose: Performs the intersection between the 2d line
-- segment (<L>, <P>) and the Curve <E>. The line
-- segment is the part of the 2d line <L> of
-- parameter range [0, <P>] (P is positive and can be
-- RealLast()). Tol is the Tolerance on the segment.
-- The order is relevant, the first argument is the
-- segment, the second the Edge.

---Purpose: Returns in <T>, <N> and <C> the tangent, normal
-- and curvature of the edge <E> at parameter value
-- <U>.
