+=head1 NAME
+
+Perl::Critic::PolicyParameter::Behavior::StringList - Actions appropriate for a parameter that is a list of strings.
+
+NOTE: Do not instantiate this class.  Use the singleton instance held
+onto by L<Perl::Critic::PolicyParameter>.
+
+
+=head1 DESCRIPTION
+
+Provides a standard set of functionality for a string list
+L<Perl::Critic::PolicyParameter> so that the developer of a policy
+does not have to provide it her/himself.
+
+
+=head1 METHODS
+
+=over
+
+=item C<initialize_parameter( $parameter, $specification )>
+
+Plug in the functionality this behavior provides into the parameter,
+based upon the configuration provided by the specification.
+
+This behavior looks for one configuration item:
+
+=over
+
+=item always_present_values
+
+Optional.  Values that should always be included, regardless of what
+the configuration of the parameter specifies, as an array reference.
+
+=back
+
+=item C<generate_parameter_description( $parameter )>
+
+Create a description of the parameter, based upon the description on
+the parameter itself, but enhancing it with information from this
+behavior.
+
+In this specific case, the always present values are added at the end.
