Do not call this script manually. It will be called automatically by the extension.

This script will be called automatically by Tweenline Engine, so you don't need to call it manually. But, if for some reason you need to simulate a step for the Tweenline Engine, you can call this script manually. None that calling the script manually is only useful for the Frames based tweens, since Seconds based tweens uses delta_time as a measure for the passed time.
