+//! The BndLib package provides functions to add a geometric primitive to a bounding box.
+//! Note: these functions work with gp objects, optionally
+//! limited by parameter values. If the curves and surfaces
+//! provided by the gp package are not explicitly
+//! parameterized, they still have an implicit parameterization,
+//! similar to that which they infer for the equivalent Geom or Geom2d objects.
+//! Add : Package to compute the bounding boxes for elementary
+//! objects from gp in 2d and 3d .
+//!
+//! AddCurve2d : A class to compute the bounding box for a curve
+//! in 2d dimensions ;the curve is defined by a tool

+//!
+//! AddSurface : A class to compute the bounding box for a surface.
