I agree that getting the hyperlinks working again for the demos would be good.
The difficulty is that the demos listed on the Help->Kepler Documentation page
reside in the outreach module whose path in the file system changes based on
the module version.

The path to the outreach module's workflows can be accessed via the java
property "outreach.workflowdir". One solution is to update
ptolemy.actor.gui.HTMLViewer to handle links with java properties. For example,
the path could be expressed using the expression language:

<a href="ptexpr:property('outreach.workflowdir') +
\"demos/getting-started/04-HelloWorld.xml\"">

To do this, HTMLViewer would use the Ptolemy expression language to parse links
beginning with ptexpr. What do you think, Christopher?
