Animated GIFs are imported as multiframe textures?

This Unity page states that animated GIFs are imported as multiframe textures that can be played back. I cannot find anything in the documentation that explains how this works and I haven’t had any luck trying to figure it out in the editor.

Does anyone know what this means and how it works?

Actually I think that went away quite a while ago when MovieTextures were introduced, and should be removed from the website.
