TiddlyWiki5 can be used to build older 2.x.x versions of TiddlyWiki from their constituent components. Doing so involves these additional features over and above those used for building TiddlyWiki5:
* The `tiddlywiki2/loadrecipe` plugin, containing a deserializer module which allows tiddlers to be loaded from TiddlyWiki 2.x.x `.recipe` files
* The `tiddlywiki2/stripcomments` plugin, containing a new viewer format for the `<$view>` widget that strips single line JavaScript comments starting `//#`
