=head1 NAME
Bencher::Scenario::Ref::Util - Benchmark Ref::Util
=head1 VERSION
This document describes version 0.003 of Bencher::Scenario::Ref::Util (from Perl distribution Bencher-ScenarioBundle-Ref-Util), released on 2024-12-04.
=head1 SYNOPSIS
To run benchmark with default option:
% bencher -m Ref::Util
To run module startup overhead benchmark:
% bencher --module-startup -m Ref::Util
For more options (dump scenario, list/include/exclude/add participants, list/include/exclude/add datasets, etc), see L<bencher> or run C<bencher --help>.
=head1 DESCRIPTION
Packaging a benchmark script as a Bencher scenario makes it convenient to include/exclude/add participants/datasets (either via CLI or Perl code), send the result to a central repository, among others . See L<Bencher> and L<bencher> (CLI) for more de...

=head1 CONTRIBUTING
To contribute, you can send patches by email/via RT, or send pull requests on
GitHub.
Most of the time, you don't need to build the distribution yourself. You can
simply modify the code, then test via:
% prove -l
If you want to build the distribution (e.g. to try to install it locally on your
system), you can install L<Dist::Zilla>,
L<Dist::Zilla::PluginBundle::Author::PERLANCAR>,
L<Pod::Weaver::PluginBundle::Author::PERLANCAR>, and sometimes one or two other
Dist::Zilla- and/or Pod::Weaver plugins. Any additional steps required beyond
that are considered a bug and can be reported to me.

=head1 BUGS
Please report any bugs or feature requests on the bugtracker website L<https://rt.cpan.org/Public/Dist/Display.html?Name=Bencher-ScenarioBundle-Ref-Util>
When submitting a bug or request, please include a test-file or a
patch to an existing test-file that illustrates the bug or desired
feature.
