An arrangement of interior-disjoint line segments with some of the \dcel records that represent it. The unbounded face \f$ f_0\f$ has a single connected component that forms a hole inside it, and this hole is comprised of several faces. The half-edge \f$ e\f$ is directed from its source vertex \f$ v_1\f$ to its target vertex \f$ v_2\f$. This edge, together with its twin \f$ e'\f$, correspond to a line segment that connects the points associated with \f$ v_1\f$ and \f$ v_2\f$ and separates the face \f$ f_1\f$ from \f$ f_2\f$. The predecessor \f$ e_{\rm prev}\f$ and successor \f$ e_{\rm next}\f$ of \f$ e\f$ are part of the chain that form the outer boundary of the face \f$ f_2\f$. The face \f$ f_1\f$ has a more complicated structure as it contains two holes in its interior: One hole consists of two adjacent faces \f$ f_3\f$ and \f$ f_4\f$, while the other hole is comprised of two edges. \f$ f_1\f$ also contains two isolated vertices \f$ u_1\f$ and \f$ u_2\f$ in its interior.

\cgal data structures as models of the \bgl graph concepts.
To this end, we offer partial specializations of the `boost::graph_traits<Graph>` for various \cgal packages.
For each such package, denoted `PACKAGE`, the partial specializations live in
the namespace `boost` and are located in the header file `CGAL/boost/graph/graph_traits_PACKAGE.h`.
Free functions are in the namespace `CGAL`, and the compiler uses argument-dependent lookup to find them.
%Euler operations, described in Section \ref BGLEulerOperations, are in the namespace `CGAL::Euler`, as the function `remove_face()` is at
the same time a low-level and an %Euler operation.
Concerning the naming conventions, we have to use those of the \sc{Bgl},
as to fulfill the requirements of the concepts defined in the \sc{Bgl}.
Concerning the naming conventions, we have to use those of the \bgl,
