+VDE is an ethernet compliant virtual network which includes tools such
+as 'vde_switch' and 'vdeqemu'. VDE switch has several virtual ports
+where virtual machines, applications, virtual interfaces and
+connectivity tools can be virtually plugged in. VDE qemu works as a
+wrapper for running qemu virtual machines that connects transparently
+to a specified vde_switch
+
+VDE is dependant upon TUN/TAP support in the Linux Kernel; this comes
+enabled by default with Slackware 12's 'generic' kernel.  To enable
+TUN/TAP support manually, you must set the following entry in your 
+kernel's '.config' file and recompile:
+	CONFIG_TUN=m
+
+## Configuration
+An init script has been provided in /etc/rc.d/rc.vde2 to use with 
+vde_switch. Edit this script and provide the TAP inteface name as 
+well as the subnet for your Virtual Switch to use.  Do NOT choose
+a subnet which is already in use. More than likely, the default 
+values will work fine.
+
+## VDE + Qemu
+A common usage for vde_switch is to be able to have emulated OS's 
+via Qemu behave as if they were actually attached to a Local Network.
+To enable this functionality with Qemu, replace any calls to 'qemu'
+with the following command:
+
+vdeqemu -net vde,vlan=0 -net nic,vlan=0,macaddr=AA:BB:CC:DD:EE:FF
+
+Note that the 'macaddr' string is optional but can prove to be
+quite useful when used in conjuction with a DHCP server (such as
+dhcpd or dnsmasq) to assign IP's based upon MAC address.
+
+Do not forget to include the options which point vdeqemu to your
+ISO image to boot along with any other options you may have used
+with 'qemu' such as -localtime, -nographic etc.
+
+## Startup
+To have this start upon each boot, add the following lines to
+/etc/rc.d/rc.local and make sure rc.vde2 is executable.
+
+	# Start vde_switch
+	if [ -x /etc/rc.d/rc.vde2 ]; then
+	   /etc/rc.d/rc.vde2 start
+	fi

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.  Line
+# up the first '|' above the ':' following the base package name, and the '|'
+# on the right side marks the last column you can put a character in.  You must
+# make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':'.
