How many times have you wished to minify in a clean way all the stylesheets and scripts of a WordPress website?
AssetsMinify takes every CSS and JS asset included using <code>wp_enqueue_style()</code> and <code>wp_enqueue_script()</code>, merges and minifies them.
You can also use AssetsMinify to create your WP theme using Compass / Sass / Less without configuring any <code>config.rb</code> or that kind of stuff.
AssetsMinify is based on Assetic library.
