 113 Parameters:

 122         * duplicate: Additionally check for messages which are translated the same to English (default off).
 123         * noexif: Don't check for EXIF messages (a bit hard and boring to translate), if you know that they are currently not translated and want to focus on other problems (default off).
 124 Check codes (ideally, all of them should result 0; all the checks are executed by default (except duplicate and language specific check blacklists in checkLanguage.inc):
 125         * untranslated: Messages which are required to translate, but are not translated.
 126         * duplicate: Messages which translation equal to fallback

 137         * 1: Show only the stub headers and number of wrong messages, without list of messages.
 138         * 2: Show only the headers and the message keys, without the message values.
 139         * 3: Show both the headers and the complete messages, with both keys and values.

 377 Run this script to check the status of a specific language in extensions, or all of them.
 378 Command line settings are in form --parameter[=value], except for the first one.
 379 Parameters:
 380         * First parameter (mandatory): Extension name, or "all" for all the extensions.
 381         * lang: Language code (default: the installation default language).
 382         * help: Show this help.
 383         * level: Show the following level (default: 2).
 384         * links: Link the message values (default off).
 385         * wikilang: For the links, what is the content language of the wiki to display the output in (default en).
 386         * whitelist: Do only the following checks (form: code,code).
 387         * blacklist: Don't do the following checks (form: code,code).
 388         * duplicate: Additionally check for messages which are translated the same to English (default off).
 389 Check codes (ideally, all of them should result 0; all the checks are executed by default (except duplicate and language specific check blacklists in checkLanguage.inc):
 390         * untranslated: Messages which are required to translate, but are not translated.
 391         * duplicate: Messages which translation equal to fallback
 392         * obsolete: Messages which are untranslatable, but translated.

 399         * unbalanced: Messages which contains unequal numbers of opening {[ and closing ]}.
 400 Display levels (default: 2):
 401         * 0: Skip the checks (useful for checking syntax).
 402         * 1: Show only the stub headers and number of wrong messages, without list of messages.
 403         * 2: Show only the headers and the message keys, without the message values.
 404         * 3: Show both the headers and the complete messages, with both keys and values.
