Could not open the Squeak image file `-version'.

There are three ways to open a Squeak image file.  You can:
  1. Put copies of the default image and changes files in this directory.
  2. Put the name of the image file on the command line when you
     run squeak (use the `-help' option for more information).
  3. Set the environment variable SQUEAK_IMAGE to the name of the image
     that you want to use by default.
