\section{Third Party Software} In this section we list the software \subsection{Standard Template Library \label{thirdparty:stl}} \cgal\ heavily uses the {\sc Stl}, and in particular adopted many of its design ideas. The {\sc Stl} comes with the compiler, but it is possible to use the compiler together with an alternative {\sc Stl} implementation. \subsection{Boost \label{thirdparty:Boost}} (www.boost.org). \subsection{GMP \label{thirdparty:GMP}} A library for multi precision integers and rational numbers. \cgal\ offers adapters for these number types. GMP (www.swox.com/gmp). \subsection{Leda \label{thirdparty:Leda}} A library of efficient data structures and algorithms. \cgal\ offers adapters to the {\sc Leda} number types. (www.algorithmic-solutions.com). \subsection{Taucs \label{thirdparty:Taucs}} A library of sparse linear solvers. It can be used by the \ccc{Surface_mesh_parametrization} package. (http://www.tau.ac.il/\~stoledo/taucs/). \subsection{zlib \label{thirdparty:zlib}} A data compression library. It is used in the examples of the \ccc{Surface_mesher} package. (www.gzip.org/zlib). \subsection{Qt \label{thirdparty:Qt}} A {\sc Gui} library. It is used in all 2D demos. (www.trolltech.com). \subsection{Coin \label{thirdparty:Coin}} An implementation of Open Inventor. It is used in the demo of the \ccc{Kinetic_data_structures} package. (www.sim.no).
