+
+//! The deferred class GccInt_Bisec is the root class for
+//! elementary bisecting loci between two simple geometric
+//! objects (i.e. circles, lines or points).
+//! Bisecting loci between two geometric objects are such
+//! that each of their points is at the same distance from the
+//! two geometric objects. It is typically a curve, such as a
+//! line, circle or conic.
+//! Generally there is more than one elementary object
+//! which is the solution to a bisecting loci problem: each
+//! solution is described with one elementary bisecting
+//! locus. For example, the bisectors of two secant straight
+//! lines are two perpendicular straight lines.
+//! The GccInt package provides concrete implementations
+//! of the following elementary derived bisecting loci:
+//! - lines, circles, ellipses, hyperbolas and parabolas, and
+//! - points (not used in this context).
+//! The GccAna package provides numerous algorithms for
+//! computing the bisecting loci between circles, lines or
+//! points, whose solutions are these types of elementary bisecting locus.
