-If you want to use SELinux, chances are you will want
-to use the distro-provided policies, or install the
-latest reference policy release from
-	http://oss.tresys.com/projects/refpolicy
-
-However, if you want to install a dummy policy for
-testing, you can do using 'mdp' provided under
-scripts/selinux.  Note that this requires the selinux
-userspace to be installed - in particular you will
-need checkpolicy to compile a kernel, and setfiles and
-fixfiles to label the filesystem.
-
-	1. Compile the kernel with selinux enabled.
-	2. Type 'make' to compile mdp.
-	3. Make sure that you are not running with
-	   SELinux enabled and a real policy.  If
-	   you are, reboot with selinux disabled
-	   before continuing.
-	4. Run install_policy.sh:
-		cd scripts/selinux
-		sh install_policy.sh
-
-Step 4 will create a new dummy policy valid for your
-kernel, with a single selinux user, role, and type.
-It will compile the policy, will set your SELINUXTYPE to
-dummy in /etc/selinux/config, install the compiled policy
-as 'dummy', and relabel your filesystem.
