  This is userd, written by Andreas H. Mueller in 1997.

 This program just writes the user-count in your /var/run/utmp to an double
7-segment-display, attached to a printerport. Run 'make config' to set the port
and the delay between updates and the real-time priority, if you want and know.
Since this is a software-multiplexing of the two displays, you'll probably see
the displays a bit flashing. Ignore this or kick userd.
It will fork themself to a daemon (you don't need to run it with an '&') and
write its PID to "/var/run/userd.pid" (Or whatever the _PATH_VARRUN in your
paths.h is).
 userd is able to count up to 99 users, but the display will show still 99 if
more than 99 users are logged in. I think this is tolerable since this
usercount is not often reached on a single system.
