  10.  * This program is public domain.  All I ask is that if you modify this *
  11.  * program and make it available to the public that you do *not* modify *
  12.  * this header nor remove my copyright logo from the program, but only  *
  13.  * extend the history modification list.  Also-- please send me a       *
