Thanks for the example code! Now I think all I need is to find out how
to launch the code from a terminal window. At http://wiki.squeak.org/squeak/1914
I found this.
"To initiate external shell processing, evaluate
''ExternalCommandShell stop'', save the image, and restart with
''squeak -headless myImage''."
It's not clear to me what will be run when that last command is
executed from a terminal window. Where would I put code like your
example code above and how does the squeak command know to execute it?
