+ *    Fixing compile error if actions file editor disabled

+ *    Revision 1.54  2002/03/24 16:18:15  jongfoster
+ *    Removing old logo

+ *    Revision 1.53  2002/03/24 16:06:00  oes

+ *    Revision 1.51  2002/03/24 13:25:43  swa
+ *    name change related issues
+ *
+ *    Revision 1.50  2002/03/16 23:54:06  jongfoster
+ *    Adding graceful termination feature, to help look for memory leaks.
+ *    If you enable this (which, by design, has to be done by hand
+ *    editing config.h) and then go to http://i.j.b/die, then the program
+ *    will exit cleanly after the *next* request.  It should free all the
+ *    memory that was used.

+ *    Added GIF images again
+ *
+ *    Revision 1.46  2002/03/07 03:48:38  oes
+ *     - Changed built-in images from GIF to PNG
+ *       (with regard to Unisys patent issue)
+ *     - Added a 4x4 pattern PNG which is less intrusive
+ *       than the logo but also clearly marks the deleted banners
+ *
+ *    Revision 1.45  2002/03/06 22:54:35  jongfoster
+ *    Automated function-comment nitpicking.
+ *
  *    Revision 1.44  2002/03/05 22:43:45  david__schmidt
  *    - Better error reporting on OS/2
  *    - Fix double-slash comment (oops)
