--
-- 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.
--
-- SEE:   https://www.mediawiki.org/wiki/Multilingual_Templates_and_Modules
--
-- 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:
--
--    {{#invoke:TNT | msg
--     | I18n/Template:Graphs.tab  <!-- https://commons.wikimedia.org/wiki/Data:I18n/Template:Graphs.tab -->
--     | source-table              <!-- uses a translation message with id = "source-table" -->
--     | param1 }}                 <!-- optional parameter -->
--
--
--    The "doc" function will generate the <templatedata> 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.
--
--    {{#invoke:TNT | doc | Graph:Lines }}
--        uses https://commons.wikimedia.org/wiki/Data:Templatedata/Graph:Lines.tab
--        if the current page is Template:Graph:Lines/doc
--
