This section is meant to help get you up and running Topics will only be briefy discussed as the full documentation is elsewhere on site. The section assumes you either downloaded jameleon-test-suite-x.x.x.zip which has everything installed (recommended) and pre-configured or you installed it yourself by reading the Jameleon install instructions and the Jiffie plug-in install instructions.
If you haven't already, be sure to read the Jameleon Getting Started section that discusses the basic principles of Jameleon.
To find out what tags are available in the jiffie plug-in, simply start up the GUI by double-clicking on "jameleon.bat" and selecting the "Function Tags" tab on the bottom left. Next, double-click on the "Functional Points" folder on the top left. Next select net, sf, jameleon, plugin follwed by jiffie. The Jiffie plug-in session and function tags are located directly in this folder and some generic tags are provided in the tags folder. d
There is also a Syntax Reference section which describes and even gives examples of using the tags. As far as whether a tag exists, the GUI is likely the best place to check.
