Newbie question!

I have never used Ruby, but I am trying to mirror a production web app
written in Ruby onto a new test server running Windows 2003 and IIS.
The production server lists ruby-web.exe as one of the files under the
web extension handling ruby requests in the IIS setup, but having
installed Ruby and Rails on the test server there is no ruby-web.exe
present, and googling hasn't turned up anything meaningful.  Can someone
tell me what ruby-web.exe is and where I can get an installer from?

Thanks.
