/* See LICENSE for more info
sxwm is a user-friendly, easily configurable yet powerful
tiling window manager inspired by window managers such as
DWM and i3
The userconfig is designed to be as user-friendly as
possible, and I hope it is easy to configure even without
knowledge of C or programming, although most people who
will use this will probably be programmers :)
