Latest version of the bjorne shell.

The attached tar file contains the latest interim version of the bjorne interpreter. I would appreciate it if some adventurous folks tried it out. I wouldn't suggest checking it into svn just yet though. It needs a lot more testing

So far, the bjorne interpreter includes the following:

• Simple commands with redirections
• Pipelines, && and ||
• Setting and expansion of shell variables, including $?.
• Backticks

So far, I have not tried integrate the bjorne interpreter with the CommandShell's command history or completion mechanisms. But that's OK. History and completion work just fine in the "redirecting" interpreter which is the one that the user sees on startup.

The interim mechanism for switching to the bjorne interpreter is type the following at the console:

  set jnode.interpreter bjorne

You can then switch back by typing:

  set jnode.interpreter redirecting

or even

  set jnode.interpreter default
