This program runs an X server after sanity-checking the environment and any options passed to it. It is meant to enhance security on multi-user systems running XFree86 4 or the X11 server from x.org, where the ability to use a startx script is needed. If you have XFree86 3, do not install this: you do not need it and it will not work. If you have no untrusted users or always run the X server from xdm, you do not need this. Trevor Johnson
