/**
 * phpMyAdmin Theme Manager
 * 2004-05-20: Michael Keck <mail_at_michaelkeck_dot_de>
 *
 * The theme manager checks the directory /themes/ for subdirectories
 * which are the themes.
 * If you're building a new theme for PMA, your theme should include
 * make a folder theme_name/ in the directory /themes which includes
 * a subdirectory css/.
 * In the css-directory you should (if you want) edit the follow files:
 *    - theme_left.css.php      // includes css-styles for the left frame
 *    - theme_right.css.php     // includes css-styles for the main frame
 *    - theme_print.css.php     // includes css-styles for printing
 *
 * If you want to use default themes for left, right or print
 * so you need not to build the css-file and PMA will use its own css.
 * If you want to use own images for your theme, you should make all
 * images (buttons, symbols, arrows) wich are included in the default
 * images directory PMA and store them into the subdirectory /img/ of
 * your theme.
 * Note:
 *     The images must be named as in the default images directory of
 *     PMA and they must have the same size in pixels.
 *     You can only use own images, if you've edit own css files.
