-! Overview

 The heart of TiddlyWiki can be seen as an extensible representation transformation engine for text and images. Given the text of a tiddler and its associated ContentType, the engine can produce a rendering of the tiddler in a new ContentType. Furthermore, it can efficiently selectively update the rendering to track any changes in the tiddler or its dependents.
 
 The primary use of the engine is to convert raw `text/vnd.tiddlywiki` WikiText into a `text/html` or `text/plain` representation for display. The transclusion and templating features of WikiText allow the engine to also be used to generate TiddlyWiki HTML files from raw tiddlers.

 The kernel boots just enough of the TiddlyWiki environment to allow it to load tiddlers and execute JavaScript modules. Plugin modules are written like `node.js` modules.
 
-There are many [[different types of module|ModuleType]]: parsers, serializers, deserializers, macros etc. It goes much further than you might expect. For example, individual tiddler fields are modules, too: there's a module that knows how to handle the `tags` field, and another that knows how to handle the special behaviour of the `modified` and `created` fields.

 Some plugin modules have further sub-plugins: the wikitext parser, for instance, accepts rules as individual plugin modules.
