showcores is a free and open source script which looks in the /cores directory on your Mac, and builds a list of what’s there and returns it as a RSS feed. Installation: To use showcores, copy the script somewhere on your Mac. Make sure that the script is executable. (`chmod +x showcores.rb` from Terminal is one way to do this.) Then in NNW, select the File > New Special Subscription > Script... menu item. Pick the scipt. Then in the info panel for the script, set the script type to "Shell".
