+If we need to specify default options, we can use the defaults
+option. For example, Zope 3 applications typically define test suites
+in modules named ftests or tests.  The default test runner behaviour
+is to look in modules named tests.  To specify that we want to look in
+tests and ftests module, we'd supply a default for the --tests-pattern
+option.  If we like dots, we could also request more verbose output
+using the -v option.
