+ The class ShellProcessSubSystemConfiguration is the main factory +for creating a shell process subsystem: a process subsystem that gathers +its data by running commands on a remote system through a shell subsystem +that's registered against the same host. By deriving from it, extenders +can create their customized shell process subsystem configuration which can +then be registered against their system types. A custom +SubSystemConfigurationAdapter can be registered for UI-specific +customizations. Possible customizations include: +
