 608 Parameters:

 610         * lang: Language code (default: the installation default language).
 611         * help: Show this help.
 612         * level: Show the following display level (default: 2).
 613         * links: Link the message values (default off).
 614         * wikilang: For the links, what is the content language of the wiki to display the output in (default en).

 616         * blacklist: Do not perform the following checks (form: code,code).
 617         * easy: Do only the easy checks, which can be treated by non-speakers of the language.
 618 Check codes (ideally, all of them should result 0; all the checks are executed by default (except language-specific check blacklists in checkLanguage.inc):
 619         * untranslated: Messages which are required to translate, but are not translated.
 620         * duplicate: Messages which translation equal to fallback
 621         * obsolete: Messages which are untranslatable, but translated.
 622         * variables: Messages without variables which should be used, or with variables which should not be used.

 624         * whitespace: Messages which have trailing whitespace.

 628         * unbalanced: Messages which contains unequal numbers of opening {[ and closing ]}.
 629 Display levels (default: 2):
 630         * 0: Skip the checks (useful for checking syntax).
 631         * 1: Show only the stub headers and number of wrong messages, without list of messages.
 632         * 2: Show only the headers and the message keys, without the message values.
 633         * 3: Show both the headers and the complete messages, with both keys and values.
