  22  * Usage: php DiffLanguage.php [lang [file]]
  23  *
  24  * lang: Enter the language code following "Language" of the LanguageXX.php you
  25  * want to check. If using linux you might need to follow case aka Zh and not
  26  * zh.
  27  *
  28  * file: A php language file you want to include to compare mediawiki
  29  * Language{Lang}.php against (for example Special:Allmessages PHP output).
  30  *
  31  * The goal is to get a list of messages not yet localised in a languageXX.php
  32  * file using the language.php file as reference.
  33  *
  34  * The script then print a list of wgAllMessagesXX keys that aren't localised, a
  35  * percentage of messages correctly localised and the number of messages to be
  36  * translated.
