+	help
+	  One common problem reported on the mailing list is the "can't
+	  access tty; job control turned off" error message, which typically
+	  appears when one tries to use a shell with stdin/stdout on
+	  /dev/console.
+	  This device is special - it cannot be a controlling tty.
+
+	  The proper solution is to use the correct device instead of
+	  /dev/console.
+
+	  cttyhack provides a "quick and dirty" solution to this problem.
+	  It analyzes stdin with various ioctls, trying to determine whether
+	  it is a /dev/ttyN or /dev/ttySN (virtual terminal or serial line).
+	  On Linux it also checks sysfs for a pointer to the active console.
+	  If cttyhack is able to find the real console device, it closes
+	  stdin/out/err and reopens that device.
+	  Then it executes the given program. Opening the device will make
+	  that device a controlling tty. This may require cttyhack
+	  to be a session leader.
+
+	  Example for /etc/inittab (for busybox init):
+
+	  ::respawn:/bin/cttyhack /bin/sh
+
+	  Starting an interactive shell from boot shell script:
+
+	  setsid cttyhack sh
+
+	  Giving controlling tty to shell running with PID 1:
+
+	  # exec cttyhack sh
+
+	  Without cttyhack, you need to know exact tty name,
+	  and do something like this:
+
+	  # exec setsid sh -c 'exec sh </dev/tty1 >/dev/tty1 2>&1'
+
+	  Starting getty on a controlling tty from a shell script:
+
+	  # getty 115200 $(cttyhack)
