+ Notes for building xrdpdev_drv.so and libxorgxrdp.so
+------------------------------------------------------
+Pre-requisites:
+ o sudo apt-get install xserver-xorg-dev
+quick and easy way to build and run the driver
+ o cd xorg/server
+ o ./test-in-home.sh
+
+ o see /etc/X11/xrdp/xorg.conf to see how things are configured
to run it
create /etc/X11/xrdp
