// privateSetGlobalObject is only required and supported on IE Mobile
on
// WinCE.
if (factory.getBuildInfo().indexOf('ie_mobile') != -1) {
factory.privateSetGlobalObject(this);
}
} catch (e) {
// Safari
if ((typeof navigator.mimeTypes != 'undefined')

factory = document.createElement("object");
factory.style.display = "none";
factory.width = 0;
factory.height = 0;
factory.type = "application/x-googlegears";
document.documentElement.appendChild(factory);
if(factory && (typeof factory.create == 'undefined')) {
// If NP_Initialize() returns an error, factory will still be
created.
// We need to make sure this case doesn't cause Gears to appear to
// have been initialized.
factory = null;
}
}
}
