description         GTK+ widget toolkit
long_description    GTK+ is a highly usable, feature-rich toolkit for creating graphical user \
                    interfaces, which boasts cross-platform compatibility and an easy-to-use \
                    API. GTK+ is written in C, but has bindings to many other popular \
                    programming languages, such as C++, Python and C#, among others.
