Template:Deprecated page

For information on this deprecated functionality, see the version {{{1}}} platform docs:
https://agileappscloud.info/{{{2}}}/index.php?title=Deprecated_page

{{deprecated_page|{version}|{wiki}}} => "see the version {version} docs at .../{wiki}/...(page with same name as current page)

The full process is this:

This pragma is added in the third stage of the deprecation process.
In the first stage, a Template:Deprecation Planned note is added at the top of existing documentation. Users can still see it, but have a warning that it will be deprecated.
In the second stage, Template:Deprecated note is added, saying that the feature has been deprecated. (Often, the process starts here. Deprecation planned is used when there is a serious impact that requires plenty of warning.)
In the third stage, the material is removed, and replaced by this pragma, which points to a previous version of the documentation to find it. (That way, searches won't surface old material, but bookmarks will still work.)
In final stage, the page is removed entirely.
