i3status - status line generator (for dzen2 and xmobar)
i3status is a small program (less than 1500 SLOC) for generating a
status bar for dzen2, xmobar, or similar programs. It is designed
to be very efficient by issuing a very small number of system calls,
as one generally wants to update such a status line every second.
This ensures that even under high load, your status bar is updated
correctly. Also, it saves a bit of energy by not hogging your CPU
as much as spawning the corresponding amount of shell commands would.
