+// RefPtr<MozURL> url;
+// nsAutoCString href("http://example.com/path?query#ref");
+// nsresult rv = MozURL::Init(getter_AddRefs(url), href);
+// if (NS_SUCCEEDED(rv)) { /* use url */ }

+// When changing the URL is needed, you need to call the Mutate() method.
+// This gives you a Mutator object, on which you can perform setter operations.
+// Calling Finalize() on the Mutator will result in a new MozURL and a status
+// code. If any of the setter operations failed, it will be reflected in the
+// status code, and a null MozURL.
+//
+// Note: In the case of a domain name containing non-ascii characters,
+// GetSpec and GetHostname will return the IDNA(punycode) version of the host.
+// Also note that for now, MozURL only supports the UTF-8 charset.
