I assume this is all temporary? This would need to be localized.

[tapted, 2014/06/12 09:09:38]

Yep - this example code is not shipped, but it might actually be easy to get a
localized string here anyway. I'll investigate.

[tapted, 2014/07/21 05:35:55]

Sadly, no easy way to do this without pulling in a dependency we don't want, or
adding a string to the build that isn't used in anything that we ship. Added a
note.

+  [appMenu addItemWithTitle:quitTitle
+                     action:@selector(terminate:)
+              keyEquivalent:@"q"];
+  [appMenuItem setSubmenu:appMenu];
+}
