Module:TNT

-- -- INTRO:  (!!! DO NOT RENAME THIS PAGE !!!) --   This module allows any template or module to be copy/pasted between --   wikis without any translation changes. All translation text is stored --   in the global  Data:*.tab  pages on Commons, and used everywhere. -- -- ATTENTION: --   Please do NOT rename this module - it has to be identical on all wikis. --   This code is maintained at https://www.mediawiki.org/wiki/Module:TNT --   Please do not modify it anywhere else, as it may get copied and override your changes. --   Suggestions can be made at https://www.mediawiki.org/wiki/Module_talk:TNT -- -- DESCRIPTION: --   The "msg" function uses a Commons dataset to translate a message --   with a given key (e.g. source-table), plus optional arguments --   to the wiki markup in the current content language. --   Use lang=xx to set language. Example: -- --                         --   --    --    The "doc" function will generate the parameter documentation for templates. --   This way all template parameters can be stored and localized in a single Commons dataset. --   NOTE: "doc" assumes that all documentation is located in Data:Templatedata/* on Commons. -- --   --        uses https://commons.wikimedia.org/wiki/Data:Templatedata/Graph:Lines.tab --       if the current page is Template:Graph:Lines/doc --
