Re: Receiving the output of CommandInterpreter.execute command from Slush

I don't think what you have here will work, the streams you pass to Slush's
command interpreter are meant for that command's use, so the output of the
command will be spit out the 'out' output stream, it won't be available from
standard in.  You might be able to do what you are trying by creating a new
SystemPrintStream around a ByteArrayOutputStream, run the command, then get
the output from your ByteArrayOutputStream.

Note that it may be more efficient for you to do whatever processing you
need to do by taking the source of PSCommand from Slush and stealing the
relevant portions for your app.  What you are doing here is going to create
lots of strings, which can lower your performance.
