=head1 NAME

Perl::Critic::Module::Build - Customization of L<Module::Build> for L<Perl::Critic>.


=head1 DESCRIPTION

This is a custom subclass of L<Module::Build> (actually,
L<Perl::Critic::Module::Build::Standard>) that enhances existing functionality
and adds more for the benefit of installing and developing L<Perl::Critic>.
The following actions have been added or redefined:


=head1 ACTIONS

=over

=item policysummary

Generates the F<PolicySummary.pod> file.  This should only be used by
C<Perl::Critic> developers.  This action is also invoked by the C<authortest>
action, so the F<PolicySummary.pod> file will be generated whenever you create
a distribution with the C<dist> or C<distdir> targets.


=item nytprof

Runs perlcritic under the L<Devel::NYTProf> profiler and generates
an HTML report in F<nytprof/index.html>.
