/* Script is free to use edit and modify, heck that is the point
of this release, I have no intention to maintain the code just put
it out so you guys can use it and modify it to fit your needs. Do
not ask me to add stuff, DO NOT ask me HOW to do stuff, read the
code all the basics you need are here, if you need more do it your
self.
