Display Rotation Tool
===

A very simple C program, that just rotates the X11 screen 90 degrees
counter-clockwise.

The main use case is to hook it up on a button to rotate my T101MT in tablet
mode without having to reach the keyboard.

### Do I know, what I am doing?

No, but I can easily know if it works. Also, a tutorial
(https://tronche.com/gui/x/xlib-tutorial/2nd-program-anatomy.html) and
Xrandr(3) man page probably know :-)
