#pod =head1 SYNOPSIS

#pod   filename = examples/file.txt
#pod
#pod =head1 DESCRIPTION
#pod
#pod This is a very, very simple L<FileGatherer|Dist::Zilla::Role::FileGatherer>
#pod plugin.  It adds all the files referenced by the C<filename> option that are
#pod found in the directory named in the L</root> attribute.  If the root begins
#pod with a tilde, the tilde is passed through C<glob()> first.
#pod
#pod Since normally every distribution will use a GatherDir plugin, you would only
#pod need to use the GatherFile plugin if the file was already being excluded (e.g.
#pod from an C<exclude_match> configuration).

#pod configuration file is located.

=head1 NAME

Dist::Zilla::Plugin::GatherFile - gather individual file(s)

=head1 VERSION

version 6.029

=head1 SYNOPSIS

  [GatherFile]
  filename = examples/file.txt

=head1 DESCRIPTION

This is a very, very simple L<FileGatherer|Dist::Zilla::Role::FileGatherer>
plugin.  It adds all the files referenced by the C<filename> option that are
found in the directory named in the L</root> attribute.  If the root begins
with a tilde, the tilde is passed through C<glob()> first.

Since normally every distribution will use a GatherDir plugin, you would only
need to use the GatherFile plugin if the file was already being excluded (e.g.
from an C<exclude_match> configuration).

=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 root

This is the directory in which to look for files.  If not given, it defaults to
the dist root -- generally, the place where your F<dist.ini> or other
configuration file is located.

=head2 prefix

This parameter can be set to place the gathered files under a particular
directory.  See the L<description|DESCRIPTION> above for an example.

=head2 filename

The name of the file to gather, relative to the C<root>.
Can be used more than once.
