mechanism of this code will result in a sub-version increase (e.g. 1.000000 to
1.000001 (1.0.1)).
-If the behaviour of C<use strictures> in normal mode changes in any way, that
-will constitute a major version increase -- and the code already checks
-when its version is tested to ensure that
+=head1 VERSIONS
+
+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;
- use strictures 1;
+Or, by passing in a C<version> option:
-will continue to only introduce the current set of strictures even if 2.0 is
-installed.
+ use strictures version => 2;
+
+=head2 VERSION 2
+
+Equivalent to:
+
+ use strict;
+ use warnings FATAL => 'all';
+ use warnings NONFATAL => 'deprecated', 'experimental';
+ # and if in dev mode:
+ no indirect 'fatal';
+ no multidimensional;
+ no bareword::filehandles;

+=head2 VERSION 1
+
+Equivalent to:
+
+ use strict;
+ use warnings FATAL => 'all';
+ # and if in dev mode:
