Choosing plug-ins to run

By default, the Eclipse application is launched with all the workspace plug-ins and all the plug-ins selected on the Plug-in Development > Target Platform preference page.

It is possible however to hand-select a subset of plug-ins to launch with on the Plug-ins tab of the launch configuration.
