Pluglets are small Java applications that are used to make minor extensions to the workbench in a simple and straightforward way. Pluglets are written in Java and reside in a pluglet project. The pluglet can be tested in the same instance of the workbench just like any other Java application. Pluglet authors can use the Java development environment, and they have access to the application programming interfaces (APIs) of the workbench plug-ins to extend and implement the existing pluglets.
