kaf24@firebug.cl.cam.ac.uk f0756c96a0 A new ACM security tool providing support to aid in the 
creation/generation of the XML security policy files for the Xen ACM
security architecture.  It is a python- based, web-based tool named
xensec_gen that allows users to create or modify XML policy files
through a browser.  The resulting XML policy files can then be copied
or moved to the appropriate location in the /etc/xen/acm-security
directory structure in order to be translated into binary and used
within the Xen system.
