JetspeedPowerTool

The JetspeedPowerTool is meant to be used by template designers to build templates for internal Jetspeed portlet applications. It hides the implementation details of the more common template actions so that future changes to said implementation have minimal effect on template.

Where applicable, methods have been marked with a BEST PRATICES meaning that this method should be used instead the synonymous code listed within the method docuementation.
