The OSP Launcher program makes it easy to distribute multiple programs and documentation in a single Java archive (jar file)
known as a Launcher package.  This directory contains Launcher packages (curriculum modules) of ready to use Ejs models.  Download
and execute these jar files.  Double clicking on a Launch Node (green arrow) in the Launcher table of contents tree runs the Ejs model.

Although models in Ejs Launcher packages are compiled and ready-to-use Java applications, Ejs Launcher packages are created in such a way 
that users can return to the Ejs authoring tool at any time to examine, modify, and adapt the models.  Ejs Launcher packages contain small 
Extensible Markup Language (XML) descriptions of each model so that right-clicking on a Launch Node passes the XML document
to Ejs thereby allowing users to examine and modify the model.  

Ejs can repackage modified models into a new jar file for redistribution.
