+ * WordPress scripts and styles default loader.
+ *
+ * Most of the functionality that existed here was moved to
+ * {@link http://backpress.automattic.com/ BackPress}. WordPress themes and
+ * plugins will only be concerned about the filters and actions set in this
+ * file.
+ *
+ * Several constants are used to manage the loading, concatenating and compression of scripts and CSS:
+ * define('SCRIPT_DEBUG', true); loads the development (non-minified) versions of all scripts and disables compression and concatenation,
+ * define('STYLE_DEBUG', true); loads the development (non-minified) versions of all CSS and disables compression and concatenation,
+ * define('CONCATENATE_SCRIPTS', false); disables compression and concatenation of scripts and CSS,
+ * define('COMPRESS_SCRIPTS', false); disables compression of scripts,
+ * define('COMPRESS_CSS', false); disables compression of CSS,
+ * define('ENFORCE_GZIP', true); forces gzip for compression (default is deflate).
+ *
+ * The globals $concatenate_scripts, $compress_scripts and $compress_css can be set by plugins
+ * to temporarily override the above settings. Also a compression test is run once and the result is saved
+ * as option 'can_compress_scripts' (0/1). The test will run again if that option is deleted.
