Animation External in the Inclusions

[Sannyasin Brahmanathaswami]

I can't find any documentation related  to the item referred to as

"Animation"   included in the list of inclusions

Dictionary entries commands like "revPlayAnimation" with association:  "animation library" all say:

"No longer supported, and included for backwards compatibility only… etc"

so, is the Animation inclusion the same library referred to in the dictionary.

Animation builder disappeared as far back as 2.5…

BR (always interested in animation options)
