 The yellow-button menu in the System Categories pane will give you the option to file out the whole of category \scat{SBE-Quinto}.
 The resulting file is more or less human-readable, but is really intended for computers, not humans.
 You can email this file to your friends, and they can file it into their own \squeak images using drag-and-drop.
