+Parsing a 3D model file and understanding the different links between bone
+matrices, keyframes and vertices is a task that can take a lot of time and
+motivation of the developer. On top of that, combining the different bone
+transform matrices for the current frame is often error prone.
+
+[rib] is an attempt to tackle these problems and might help you save time.
+Current features of [rib] include:
+
+- Support of collada files coming from the latest Blender version.
+- Precomputation of the bone matrices expressed in the world space so that you
+  just have to pass it to your shader for traditional GPU skinning.
+- Interpolation between keyframes
+- (De)/serialization in binary thanks to [bincode]
+
+[rib] can be greatly extended, for example with the support of other format
+handling skeleton data, such as the [glTF] format.
+Contributions are more than welcome.
