-\ingroup PkgBooleanSetOperations2
-
-The default <span class="textsc">Dcel</span> class template used by the
-`General_polygon_set_2` and `General_polygon_with_holes_2` class templates.
-This template is parameterized by a traits class, which is a model of the
-`GeneralPolygonSetTraits_2` concept. It uses the types `Traits::Point_2` and
-`Traits::X_monotone_curve_2` nested in the traits class to instantiate the
-base vertex, halfedge, and face types, respectively. Recall, that the
-<span class="textsc">Dcel</span> stores the incidence relations between
-the arrangement calls and the geometric data attached to vertices and edges.
-This <span class="textsc">Dcel</span> also stores data used to determine
-whether a face is interior and exterior of the general polygon set, and
-additional data used for optimizations.
-
-You need to override this default and use a different
-<span class="textsc">Dcel</span> only if you intend to obtain the underlying
-arrangement of the general polygon set and process it further.
