=head1 NAME

Dist::Zilla::Plugin::ManifestSkip - decline to build files that appear in a MANIFEST.SKIP-like file

=head1 VERSION

version 6.031

=head1 DESCRIPTION

This plugin reads a MANIFEST.SKIP-like file, as used by L<ExtUtils::MakeMaker>
and L<ExtUtils::Manifest>, and prunes any files that it declares should be
skipped.

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 ATTRIBUTES

=head2 skipfile

This is the name of the file to read for MANIFEST.SKIP-like content.  It
defaults, unsurprisingly, to F<MANIFEST.SKIP>.
