#    Este foi um meio divertido que encontrei para    #
#  testar a compatibilidade no uso de arrays entre o  #
# bash e o ksh. Se alguem quiser desenvolver a rotina #
#   em que o adversario comeca jogando, sinta-se a    #
#  vontade, porem nao esqueca de mandar-me o modulo   #
#             para incorpora-lo ao meu.               #
#-----------------------------------------------------#
#  This program was developed as a funny way to test  #
#  the compatibility between arrays in ksh and bash.  #
# Feel free for develop the module that the opponent  #
# start playing, but don't forget to send me the new  #
#     routine because I'll attach it at this one.     #
