This the Dist::Zilla manpage plugin appends files in a directory to files
being gathered for the distribution.

When using this plugin, be thoughtful about the order in which you want
files to be modified. For example, if you are appending Pod, it makes a big
difference if you append before or after a plugin like C<PodWeaver>. If you
list this plugin first, the Pod will be appended before weaving and the
added Pod will wind up in the middle of the generated Pod. If this plugin
is listed last, the Pod will be appended after weaving and will follow the
generald Pod from C<PodWeaver>.

If appending a C<__DATA__> section, be sure to put this plugin last among
plugins that modify your files.
