lessphp for WordPress: filter for stylesheet URLs so that if there is a corresponding file with a .less extension and that file is newer than this .css file, then lessphp is invoked to rebuild the stylesheet: the theme comment header is preserved.
<?php
/**

* located in <TEMPLATEPATH/lessphp/lessc.inc.php> This filter may be invoked
* in header.php as follows:
* <link rel="stylesheet"
* href="<?php echo apply_filters('style_loader_src', get_stylesheet_uri(), null); ?>"

Concatenates scripts and then minifies and optimizes them using Google's Closure Compiler. For non-concatenable scripts, removes default WordPress 'ver' query param so that Web-wide cacheability isn't broken for scripts on CDNs like ajax.googleapis.com.
Please see: http://svn.wp-plugins.org/optimize-scripts/trunk/
