 %description
 synfig is a vector based 2D animation package. It is designed to be capable of producing feature-film quality animation. It eliminates the need for tweening, preventing the need to hand-draw each frame. synfig features spatial and temporal resolution independence (sharp and smooth at any resolution or framerate), high dynamic range images, and a flexible plugin system.
