+  <p>You can, optionally, create source and binary RPM packages for LLVM. These
+  may make it easier to get LLVM into a distribution. This can be done with
+  the following commands:</p>
+  <pre>
+  make dist        # Build the distribution source tarball
+  make dist-check  # Check that the source tarball can build itself.
+  cp llvm-M.m.tar.gz /usr/src/redhat/SOURCES  # Required by rpmbuild

+  make rpm  # for binary rpm

+  <p>First, use "make dist" to simply build the distribution. Any
   failures need to be corrected (on the branch). Once "make dist" can be
   successful, do "make dist-check". This target will do the same thing as the
-  'dist' target but also test that distribution to make sure it works. This
