32//! Implements construction algorithms for an arc of
33//! parabola in the plane. The result is a Geom2d_TrimmedCurve curve.
34//! A MakeArcOfParabola object provides a framework for:
35//! - defining the construction of the arc of parabola,
36//! - implementing the construction algorithm, and
37//! - consulting the results. In particular, the Value
38//! function returns the constructed arc of parabola.
