You might try 'ttro' - this is the type used by SimpleText (nee TeachText)
to indicate a 'read-only' text file - those are the files that look like
folded-up newspapers.  Seems appropriate for the sources file.  StuffIt
shouldn't touch it, but it means that most text editors won't open it
either, and  it will display an error dialog upon opening (>32 K - the
limit for SimpleText).

Ideally, the entire Squeak suite on Mac should follow the rules, including
setting up app/doc icons, bundles, and file refs, so that images will
naturally open the VM, appropriate document descriptions show up in Get
Info, etc.  It's rather un-Macish to be so generic.

If you'd like some help with this, I can certainly assist.  I've shipped
many commercial Mac applications, and have this sort of thing down.  All
you'll really have to do is include some resources and set the "bundle" bit
in the application.
