+   off.c - Switch the Mustek 600 II N off
+
+   This utility accesses the I/O-ports directly and must therefore be
+   run with euid root, or must at least have access to /dev/port.
+   Compile with:
+   gcc -DHAVE_SYS_IO_H -O2 -Wall -s -o off off.c
+   The -O2 optimization is needed to allow inline functions !
