+      An open source library for building playback and review applications for
+      visual effects, film, and animation.
+
+      The library can render and playback timelines with multiple video clips,
+      image sequences, audio clips, and transitions. Examples are provided for
+      integrating the library with Qt and OpenGL applications.
