+=head1 Customizing patchlevel to advertise your local patches
+
+You can advertise your custom local patches by using patchlevel.h as a
+standalone Perl script.
+
+=head2 Sample usage:
+
+               perl -x patchlevel.h "This is a custom patch"
+
+=head1 Disabling known flapping tests
+
+Some tests could fail under heavy load, whereas in most cases
+they would simply succeed. Usually, continuous integration systems
+will at one point or the other reach that problem.
+
+To disable these known tests, please set the environment
+variable CI to true.
+
+        CI=true
