    Alembic will not attempt to store a representation of the network of computations (rigs, basically)
    which are required to produce the final, animated vertex positions and animated transforms.
 
-:abbr:`TL;DR (Too long; did not read.)`: Alembic can be used to write an animated mesh to
-a drive, and read it back quickly and efficiently. This means that a mesh can be animated with
-a very CPU-intensive rig and then 'baked' to an Alembic file. Finally it can be load into the shot file
-for shading and lighting with only moderate CPU usage.

-Support for the Alembic file format was introduced in
-`Blender 2.78 <https://www.blender.org/download/releases/2-78>`__.

 Due to the Open Source nature of the Alembic standard as well as
 the C++ library implementing that standard, **Blender can be used in a hybrid pipeline**.
 For example, other software, such as Houdini or Maya, can export files to Alembic,
