  Revision 1.12  1996/12/20 16:49:27  wenger
  Conditionaled out RTree code for libcs and attrproj.

  Revision 1.11  1996/12/15 06:52:31  donjerko
  Added the initialization and shutdown for RTree code.

  Revision 1.10  1996/11/26 09:29:59  beyer
  The exit code now removes the temp directory for its process.
  This could be more portable -- right now it just calls 'rm -fr'.

  Revision 1.9  1996/09/04 21:24:48  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 1.8  1996/05/20 18:44:59  jussi
  Merged with ClientServer library code.

  Revision 1.7  1996/05/20 17:47:37  jussi
  Had to undo some previous changes.

  Revision 1.6  1996/05/09 18:12:11  kmurli
  No change to this makefile.

  Revision 1.5  1996/04/22 21:10:42  jussi
  Error message printed to console includes file name and line
  number.

  Revision 1.4  1996/04/16 19:45:35  jussi
  Added DoAbort() method and DOASSERT macro.

  Revision 1.3  1996/01/11 21:51:14  jussi
  Replaced libc.h with stdlib.h. Added copyright notice.

  Revision 1.2  1995/09/05 21:12:45  jussi
  Added/updated CVS header.
