+\cgalPkgDesc{The polyhedral surface mesh class provided by this package is a data structure
  that can be used as halfedge data structure or polyhedral surface. It is
 an alternative to the packages \ref PkgHDSSummary and \ref PkgPolyhedronSummary.
 The main differences are that it is indexed based and not pointer based,
