                                 FileDate
                          written by Joseph Hodge

         The purpose of this utility is to allow a person to change the file
     dates of any files he/she chooses, I am sure there is probably utilities
     like this around somewhere, but I have not seen them. This version does
     not support wildcards, perhaps future versions will.
