In its simplest form, Animay is a command-line program, which will take an animation file (which usually have the extension ".anp"), and generate the images for each frame of the animation. These images may then be played as an animation, or compiled into an animation format such as mpeg.
Animay also contains a Motif-based GUI spline editor, although this will only work on a unix platform with the Motif libraries.
