@@lang =

There are better ways to extend a translated string, but I keep the ‘wild-card’ for historical reasons.

@@lang_file = 
format("%s%s", RD, 'LANG')
@@tr = 
YAML::load_file("#{RD}translations")

      @@lang.chomp!.downcase! if @@lang

end

.trl(t) ⇒ Object

    puts "\nTRANSLATION MISSING: \"" << t << "\""
  end
  lt ||= t
  return lt
end

.trl_words(str) ⇒ Object

Translate in the given string only those words for which a translation is found. This is useful for mixed content like dates: “Friday, 8. July 2011”. As the order changes with the locale, alphabetic content is matched and the remainder discarded.
