I can't seem to find out how to do this...  Thanks for any help.

I have Ruby installed on my Mac (OS X Leopard) and it works fine from
the terminal window.  I'd like to create a dock shortcut or be able to
just double-click the .rbw file to run it.  When I click it, it just
brings up a window that shows the code rather than running it.

Is there a way to put a shortcut down in the dock so I can just click
it to run the particular Ruby script (or click it from within
Finder)?

Thanks.
