Decode eAccelerator

Does anyone know how can i decode the encoded php files with eAccelerator.

Example:

<?php if (!is_callable("eaccelerator_load") &&  !@dl("eAccelerator.so")) { die("Du hast kein eAcellerator installiert,  was aber zwingend erforderlich ist. <a  href=\"http://eaccelerator.sourceforge.net/\">eAccelerator</a>");  }eaccelerator_load('eJxzdXR2dvVxDXIM8Q9iYGZgYGBiYG   YHUumpJdmplUAeA4TjDeSgAiYkth0j48/GeoapIDYHiGABYjYUlTlo2pmR2BqMzAJAykY/KT+l0o7LRj+jJDfHjsufA2EgMgAARGQRug==');  ?>
