This is a Meteor package used to as a wrapper for the Bootstrap Material Design.
The package is sourced from the recently unsupported meteor code.
Material Design for Bootstrap is a Bootstrap V3 compatible theme; it is an easy way to use the new Material Design guidelines by Google in your Bootstrap 3 based application. Just include the theme, after the Bootstrap CSS and include the JavaScript at the end of your document (just before the
</body>tag), and everything will be converted to Material Design (Paper) style.
