## WEP-KEY BIN Viewer for Spoonwep
## (ASCII to BINARY Changer for Spoonwep / Spoonwep2)

##           http://freebsd.ai-line.com/  by sio (Japan)
## ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

## How to use. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
#  1.Permission change to 0700.
#  2.When Spoonwep is finished, this running.
#  3.Executes this.
#  4.After that, Please give me a mail(sio<at>ai-line.com).
#    Girl or Japanese limitation ;-)
