// Summary: This is a simple prim animation script. Just add this script // to your object and a dialog will automatically pop up for you to use.

// Features: // -Single script "Prim Puppeteer" like animation tool // -Playback controllable through external scripts // -Animation is scalable and resizeable // -On-touch trigger built-in // -Completely free and open sourced

// License: // You are welcome to use this anyway you like, even bring to other grids // outside of Second Life. You are welcomed to sell it if you've made your // own improvements to it. This is effectively public domain. Have fun.
