+
+Depending on the version of strictures requested, different warnings will be
+enabled.  If no specific version is requested, the current version's behavior
+will be used.  Versions can be requested using perl's standard mechanism:
+
+  use strictures 2;
+
+Or, by passing in a C<version> option:
+
+  use strictures version => 2;
