Decode some IonCube files

I have about 20 PHP files encoded with what seems to be an IonCube encoding. I need someone to decode these files for me. This is what the header in the files looks like <?php //00426 if(!extension_loaded('ionCube Loader')){$__oc=strtolower(substr(php_uname(),0,3));$__ln='ioncube_loader_'.$__oc.'_'.substr(phpversion(),0,3).(($__oc=='win')?'.dll':'.so');@dl($__ln);if(function_exists('_il_exec')){return _il_exec();}$__ln='/ioncube/'.$__ln;$__oid=$__id=realpath(ini_get('extension_dir'));$__here=dirname(__FILE__);if(strlen($__id)>1&&$__id[1]==':'){$__id=str_replace('\\','/',substr($__id,2));$__here=str_replace('\\','/',substr($__here,2));}$__rd=str_repeat('/..',substr_count($__id,'/')).$__here.'/';$__i=strlen($__rd);while($__i--){if($__rd[$__i]=='/'){$__lp=substr($__rd,0,$__i).$__ln;if(file_exists($__oid.$__lp)){$__ln=$__lp;break;}}}@dl($__ln);}else{die('The file '.__FILE__." is corrupted. Ensure that you use binary mode when transferring files with FTP and disable the 'TAR smart cr/lf feature' if using WinZIP\n");}if(function_exists('_il_exec')){return _il_exec();}echo('Site error: the file <b>'.__FILE__.'</b> requires the ionCube PHP Loader '.basename($__ln).' to be installed by the site administrator.');exit(199); ?>
