2009-09-11 Till Straumann <Till.Straumann@TU-Berlin.de>

	* psim-top.in, psim-bottom: Added support for options
	-d (print device tree and exit), -h (usage info) and
	-n (enable NIC support).

	* psim-gdb-bottom: Added support for options -s (force sysv IPC),
	-h (usage info) and -n (enable NIC support).
	Allow user to override GDB variable from environment.

	* psim-shared: cat NIC properties into device file if the
	user had specified '-n'.

	* runtest-top.in: removed unsupported options -o, -d from
	usage info.
