+The target language can be specified as either a number or a string.
+If a string is given, it is looked up in the hash
+C<%Lyrics::Fetcher::LyricsTranslate::LANGUAGES> which maps language
+names to their numerical identifiers. The hash was generated from the
+website, and it might be outdated.
+
+The target language is passed as the third argument to the B<fetch>
+method. If using the module via L<Lyrics::Fetcher>, the target
+language cannot be set and defaults to English.
