32//! Implements construction algorithms for a line
33//! segment in 3D space.
34//! Makes a segment of Line from the 2 points <P1> and <P2>.
35//! The result is a Geom_TrimmedCurve curve.
36//! A MakeSegment object provides a framework for:
37//! - defining the construction of the line segment,
38//! - implementing the construction algorithm, and
39//! - consulting the results. In particular, the Value
40//! function returns the constructed line segment.
