description                 Open Source C++/Python mapping toolkit.
long_description            Mapnik is a Open Source tookit for developing mapping \
                            applications. It is written in C++ and there are \
                            Python bindings to facilitate fast-paced agile \
                            development. It can comfortably be used for both \
                            desktop and web development. \
                            \
                            Mapnik is about making beautiful maps. It uses the \
                            AGG library and offers world class anti-aliasing \
                            rendering with subpixel accuracy for geographic \
                            data. It is written from scratch in modern C++ and \
                            does not suffer from design decisions made a decade \
                            ago. When it comes to handling common software tasks \
                            such as memory management, filesystem access, \
                            regular expressions, parsing and so on, Mapnik \
                            does not re-invent the wheel, but utilises best of \
                            breed industry standard libraries from boost.org.
