// FIXME: For each human language there should be a mapping from its

// In addition, for the currently selected language, there should be a

// the current language is French, that mapping would map "el" to
// "grec", which is french for Greek.  Keeping these mappings
// conceptually separate avoids having to load all names of all

// To ease debugging, and to save space in the common case, the
