Extensible via Plugins
	• Plugins can: – Define experiment specific utilities (event display, analysis utilities, specialized tables). – Define data interfaces to handle new types of data. – Define new plotting routines (e.g. to display special display). – Add menus, create control areas, consoles, and output pages. – Plugins will be more flexible in JAS 3.0 (see discussion of FreeHEP application framework, later).
