 slstatus - suckless status
 ==========================

 - Battery percentage/state/time left
-- Cat (read file)
 - CPU usage
 - CPU frequency
 - Custom shell commands

 -------------
 slstatus can be customized by creating a custom config.h and (re)compiling the
 source code. This keeps it fast, secure and simple.
