   3   * WordPress scripts and styles default loader.
   4   *
   5   * Several constants are used to manage the loading, concatenating and compression of scripts and CSS:
   6   * define('SCRIPT_DEBUG', true); loads the development (non-minified) versions of all scripts and CSS, and disables compression and concatenation,
   7   * define('CONCATENATE_SCRIPTS', false); disables compression and concatenation of scripts and CSS,
   8   * define('COMPRESS_SCRIPTS', false); disables compression of scripts,
   9   * define('COMPRESS_CSS', false); disables compression of CSS,
  10   * define('ENFORCE_GZIP', true); forces gzip for compression (default is deflate).
  11   *
  12   * The globals $concatenate_scripts, $compress_scripts and $compress_css can be set by plugins
  13   * to temporarily override the above settings. Also a compression test is run once and the result is saved
  14   * as option 'can_compress_scripts' (0/1). The test will run again if that option is deleted.
