A Tiddler is the fundamental unit of content in a TiddlyWiki. In TiddlyHoster, each tiddler exists in a bag and may be accessed through the TiddlyWeb HTTP API. For example there is a copy of this tiddler available at http://hoster.peermore.com/bags/help/tiddlers/tiddler.txt

A Tiddler may contain human readable content, binary data, or JavaScript code.
