+=head1 NAME
+
+Perl::Critic::Policy::Modules::RequireFilenameMatchesPackage - Package declaration must match filename.
+
+=head1 AFFILIATION
+
+This Policy is part of the core L<Perl::Critic> distribution.
+
+

+
+The package declaration should always match the name of the file that
+contains it.  For example, C<package Foo::Bar;> should be in a file
+called C<Bar.pm>.
+
+
+=head1 CONFIGURATION
+
+This Policy is not configurable except for the standard options.
