- *
- * Overview
- * --------
- * Tiny client-side JavaScript templating library.
- *
- * Why? This script is:
- *
- * * less than 4k minified (see `luigi-template.min.js`),
- *
- * * has no external dependencies (no jQuery/YUI/Sensha),
- *
- * * works in browsers as old as IE8, and
- *
- * * MIT licensed (use for whatever, I don't care)
- *
- * Usage
