Command Line StoppingStarting of WF Servers

I know in Workflow 6.1 there are new command line utilities to stop and start a particular workflow server (for example, the process server). Has anyone figured out a way to do this in WF 6.0.2? We tried using the 6.1 jar file, but we can’t get it to work.

Maybe by using Unix commands, broker documents, other? They connect to the WF server using WF Administrator and stop/start particular servers, so there has to be a way. Was wondering if anyone out there figured it out.
