  Revision 1.13  1996/12/15 20:21:42  wenger
  Added '-noshm' command line flag to allow user to disable shared memory;
  temporarily disabled RTree stuff.

  Revision 1.12  1996/12/03 20:24:09  jussi
  Removed unused command line parameters. Changed BufPolicies().

  Revision 1.11  1996/11/23 21:23:11  jussi
  Removed variables and methods not used anywhere.

  Revision 1.10  1996/10/07 22:53:50  wenger
  Added more error checking and better error messages in response to
  some of the problems uncovered by CS 737 students.

  Revision 1.9  1996/09/12 18:37:45  wenger
  Added optional delay before drawing images.

  Revision 1.8  1996/09/05 20:00:12  jussi
  Added screenWidth and screenHeight command line arguments.

  Revision 1.7  1996/09/04 21:24:49  wenger
  'Size' in mapping now controls the size of Dali images; improved Dali
  interface (prevents Dali from getting 'bad window' errors, allows Devise
  to kill off the Dali server); added devise.dali script to automatically
  start Dali server along with Devise; fixed bug 037 (core dump if X is
  mapped to a constant); improved diagnostics for bad command-line arguments.

  Revision 1.6  1996/08/23 16:55:36  wenger
  First version that allows the use of Dali to display images (more work
  needs to be done on this); changed DevStatus to a class to make it work
  better; various minor bug fixes.

  Revision 1.5  1996/04/18 18:12:59  jussi
  Replaced 'postScript' member variable and method with more appropriate
  name 'batchFile.'

  Revision 1.4  1996/02/05 23:56:55  jussi
  Added DEVise logo display.

  Revision 1.3  1996/01/27 00:22:11  jussi
  Added _postScript variable.

  Revision 1.2  1995/09/05 21:12:53  jussi
  Added/updated CVS header.
