<!--
The following state tiddlers control the tour. They should not be directly modified,
but rather use the appropriate procedure to ensure that all the associated actions are performed.
$:/config/CurrentTour: title of current tour definition tiddler
$:/state/tour/step: title of current step of the tour
These config tiddlers may be changed directly as required:
$:/config/ShowTour: "show" (default) or "hide"
$:/config/AutoStartTour: "no" (default) or "yes"
Tour definition tiddlers have the following fields:
tags: must include $:/tags/Tour
tour-tag: name of tag used to define tour step sequence
logo: title of tiddler containing logo of tour
description: brief description of the tour
text: longer description of the tour
