uninstall.php (4046B)

      3  * Breadcrumb NavXT - uninstall script
      4  *
      5  * uninstall script based on WordPress Uninstall Plugin API
      6  * 
      7  * 
      8  * Because bcn_admin->uninstall() does not work with WPMU, 
      9  * an uninstaller class has been written, that encapsulates 
     10  * the uninstall logic and calls bcn_admin->uninstall() 
     11  * when applicable.
     12  * 
     13  * @see http://codex.wordpress.org/Migrating_Plugins_and_Themes_to_2.7#Uninstall_Plugin_API
     14  * @see http://trac.mu.wordpress.org/ticket/967
     15  *
     16  * this uninstall.php file was executed multiple times because 
     17  * breadcrumb navxt (until 3.3) constsisted of two plugins:
     18  *
     19  *	1.) breadcrumb_navxt_class.php / Core
     20  *  2.) breadcrumb_navxt_admin.php / Adminstration Interface
