=head1 NAME

Dist::Zilla::Plugin::Manifest - build a MANIFEST file

=head1 VERSION

version 6.025

=head1 DESCRIPTION

If included, this plugin will produce a F<MANIFEST> file for the distribution,
listing all of the files it contains.  For obvious reasons, it should be
included as close to last as possible.

This plugin is included in the L<@Basic|Dist::Zilla::PluginBundle::Basic>
bundle.

=head1 PERL VERSION

This module should work on any version of perl still receiving updates from
the Perl 5 Porters.  This means it should work on any version of perl released
in the last two to three years.  (That is, if the most recently released
version is v5.40, then this module should work on both v5.40 and v5.38.)

Although it may work on older versions of perl, no guarantee is made that the
minimum required version will not be increased.  The version may be increased
for any reason, and there is no promise that patches will be accepted to lower
the minimum required perl.

=head1 SEE ALSO

Dist::Zilla core plugins:
L<@Basic|Dist::Zilla::PluginBundle::Manifest>,
L<ManifestSkip|Dist::Zilla::Plugin::ManifestSkip>.

Other modules: L<ExtUtils::Manifest>.
