This program is for non-military use only. For details on what that licencing restriction means and why I restricted this software that way, see http://mindprod.com/contact/nonmil.html If you incorporate any of my code in your programs, they too must be marked for non-military use only. However it is not your responsibility to enforce that restriction.
