Module documentation[view] [edit] [history] [purge]

This module is used to substitute a page's contents. It can be used on all existing pages, including redirects. (That is, it will return the contents of the redirect page itself, not the contents of the redirect target page.) However, it will only return the page's wikitext as-is; it will not work properly on pages that use safesubst, <noinclude>...</noinclude> tags, <includeonly>...</includeonly> tags, or <onlyinclude>...</onlyinclude> tags. For this reason this is an experimental module, and is not intended for widespread use.
