// loaded. For example, the client can look for the "browser_action" manifest
// key as documented at https://developer.chrome.com/extensions/browserAction.

// - Can access chrome.* JavaScript APIs if allowed by the manifest. Visit
// chrome://extensions-support for the list of extension APIs currently
// supported by CEF.
// - Main frame navigation to non-extension content is blocked.
// - Pinch-zooming is disabled.
// - CefBrowserHost::GetExtension returns the hosted extension.
// - CefBrowserHost::IsBackgroundHost returns true for background hosts.

// and usage documentation.
