Example

To create a packlet:

1. Write a manifest.xml file defining the packlet.

2. Write template files for launch scripts.

3. Run the packlet builder to generate your packlet:

            packlet manifest.xml path_to_packlet/yourPacklet.class
         

4. Test the packlet:

            java -cp path_to_packlet yourPacklet
