 *         entry; you may need to add an #include or two for is_number() and
 *         atoi().
 *          'dice' will roll two six-sided dice.  'dice' followed by a number
 *         will restrict the number to 1-10 and roll that number of six-sided
 *         dice.  'dice' followed by two numbers will restrict the first number
 *         to 1-10 and the second number to 2-20 and roll (first number) dice
 *         of (second number) sides.  The values of all dice rolled are listed,
 *         and the total.
 *          If you have a 'snippets' help file, I would appreciate an entry
 *         similar to:  Dice code by Cameron Taylor.
