RxStartx is a collection of REXX scripts that will allow you to start XFree86/2 up to 2 times faster and will allow you to do lots of tweaking during both startup and shutdown. As it really speeds up X loading it is a must-have thing for X/2 users. The man to praise for this useful tool is Alex Samorukov,
Main features of RxStartx:
* more quickly launches XFree86 than startx does (makes no pause after xserver start)
* before xserver launching it checks availability of the X11 port
* includes internal support for FONT server
* is simple in configuring and written on REXX which allows adopting it for
* your special needs.
