description         Cross-platform multi-media development API
long_description    Simple DirectMedia Layer is a cross-platform development library \
                    designed to provide low-level access to audio, keyboard, mouse, \
                    joystick and graphics hardware via OpenGL and Direct3D. This port \
                    is aimed at supporting macOS PowerPC and uses X11 backend.
