-// Utility for setting chrome.*.lastError.
-//
-// A utility here is useful for two reasons:
-//  1. For backwards compatibility we need to set chrome.extension.lastError,
-//     but not all contexts actually have access to the extension namespace.
-//  2. When calling across contexts, the global object that gets lastError set
-//     needs to be that of the caller. We force callers to explicitly specify
-//     the chrome object to try to prevent bugs here.
