+\begin{ccPkgDescription}{Halfedge Data Structures  \label{Pkg:HDS}}
+\ccPkgSummary{A halfedge data structure (abbreviated as HalfedgeDS, or
+HDS for template parameters) is an edge-centered data structure
+capable of maintaining incidence informations of vertices, edges and
+faces, for example for planar maps, polyhedra, or other orientable,
+two-dimensional surfaces embedded in arbitrary dimension. Each edge is
+decomposed into two halfedges with opposite orientations. One incident
+face and one incident vertex are stored in each halfedge. For each
+face and each vertex, one incident halfedge is stored. Reduced
+variants of the halfedge data structure can omit some of these
+informations, for example the halfedge pointers in faces or the
+storage of faces at all.}
