a17ab98005 - Remove the __FBSDID and put the $FreeBSD$ tag in the comment above,
so that including this file more than once works.

3d3bf229f9 Add a generic LED driver for flashing lamps.
The hardware driver decides the name under /dev/led and provides
the function to turn the lamp on/off.

All leds are serviced by a single timeout which runs at a basic rate
of hz/10.

The LED is controlled by ascii strings as follows.

0	Turn off.
1	Turn on.
f	Flash: _-
f2	Flash: __--
f3	Flash: ___---
f4...f9 etc.
d%d	Digits.  "d12": -__________-_-______________________________
s%s	String, roll your own:
	'a-j' gives on for (1...10)/10 sec.
	'A-J' gives on for (1...10)/10 sec.
	'sAaAbBa': _-_--__-
m%s	Morse
	'.' dot
	'-' dash
	' ' letter space
	'\n' word space

My mdoc skills do not reach to express that.
