+To compile and install run "make install"; if it fails or you need to reinstall 
+run "make clean" first or the build will fail, at least that is what I have 
+found under 2.6.10.
+
+Other important items:
+1)     You will need to have your xen0 kernel compiled with HMAC_SUPPORT 
+       2.6.x = (MAIN MENU: Cryptographic Options -> HMAC Support)
+       BEFORE running "make install".
+
+2)     You will want at least some of the other alogorithms listed under
+       "Cryptographic Options" for the kernel compiled as modules.
+
+3)     You will want the networking IPsec/VLAN options compiled in as modules
+       2.6.x = (MAIN MENU: Device Drivers -> Networking Support -> 
+                               Networking Options ->
+                                       IP: AH transformation
+                                       IP: ESP transformation
+                                       IP: IPComp transformation 
+                                       IP: tunnel transformation
+
+                                       IPsec user configuration interface
+       
+                                       802.1Q VLAN Support
+
+4)     The module (vnet_module) will not properly load from the command line
+       with a "modprobe vnet_module".  Use network-vnet to properly configure
+       your system and load the module for you.
+
+Please refer to the additional documentation found in tools/vnet/doc for
+proper syntax and config file parameters.
