The plugin provides an editor for PEPA model input files. The editor contributes a top-level menu item to the workbench bar through which all the PEPA-related tools are accessible. Additional information is provided via workbench views. The PEPA perspective provides a customisable layout for those views in the workbench.
To open the PEPA Perspective, select Window > Open Perspective > Other. Then select PEPA and press OK to finish.
