  IotStartup [help|-?|-h|--help]

Examples:
  IotStartup list                   // list installed applications
  IotStartup list headed            // list installed headed applications
  IotStartup list headless          // list installed headless applications
  IotStartup list MyApp             // list installed applications that match pattern MyApp

  IotStartup add headed MyApp       // add headed application that matches pattern MyApp.  Pattern must match only one application.
  IotStartup add headless Task1     // add headless applications that match pattern Task1

  IotStartup remove headless Task1  // remove headless applications that match pattern Task1
  IotStartup remove headless suppress Task1  // remove headless applications that match pattern Task1 and suppress WNF notification

  IotStartup startup                // list headed and headless applications registered for startup
  IotStartup startup MyApp          // list headed and headless applications registered for startup that match pattern MyApp
  IotStartup startup headed MyApp   // list headed applications registered for startup that match MyApp
  IotStartup startup headless Task1 // list headless applications registered for startup that match Task1

  IotStartup run MyApp              // Start app identified by MyApp (see 'iotstartup list')
  IotStartup stop MyApp             // Stop app identified by MyApp (see 'iotstartup list')
