+=head1 NAME
+
+Perl::Critic::Exception::AggregateConfiguration - A collection of a set of problems found in the configuration and/or command-line options.
+
+=head1 DESCRIPTION
+
+A set of configuration settings can have multiple problems.  This is
+an object for collecting all the problems found so that the user can
+see them in one run.
+
+
+=head1 METHODS
+
+=over
+
+=item C<add_exception( $exception )>
+
+Accumulate the parameter with rest of the exceptions.
+
+
+=item C<add_exceptions_from( $aggregate )>
+
+Accumulate the exceptions from another instance of this class.
+
+
+=item C<exceptions()>
+
+Returns a reference to an array of the collected exceptions.
+
+
+=item C<add_exception_or_rethrow( $eval_error )>
+
+If the parameter is an instance of
+L<Perl::Critic::Exception::Configuration> or
+L<Perl::Critic::Exception::AggregateConfiguration>, add it.
+Otherwise, C<die> with the parameter, if it is a reference, or
+C<confess> with it.  If the parameter is false, simply returns.
+
+
+=item C<has_exceptions()>
+
+Answer whether any configuration problems have been found.
+
+
+=item C<full_message()>
+
+Concatenate the exception messages.  See
+L<Exception::Class/"full_message">.
