In this post, You can find ANT script that automates some of the main HTML 5 tasks as are versioning, running tests, generating image sprite-sheets, minifying javascripts and css, compressing html, inline scripts and styles and finally making release.

This document is just a simple reference on how to use doT.js JavaScript template engine in browser.
