New in: 5.1.18 The system tag
$:/tags/RawMarkupWikified/TopBody marks wikified tiddlers to be included as raw markup at the top of the
<body> section in the generated HTML file.
Note that the wiki must be saved and reloaded in order for a raw markup tiddler to take effect. Also note that global macros are not available by default within raw markup tiddlers; you can use the ImportVariablesWidget to explicitly import them.
