+This test will not run unless you set MOO_TEST_MD to a true value.
+
+  Valid values are:
+
+     all                  Test every dist which depends on Moose except those
+                          that we know cannot be tested. This is a lot of
+                          distros (hundreds).
+
+     Dist::1,Dist::2,...  Test the individual dists listed.
+
+     MooX                 Test all Moo extension distros.
+
+     1                    Run the default tests. We pick 200 random dists and
+                          test them.
