=head1 VERSION

=head1 WARNINGS

=head2 STOP

You probably don't want to use this module. You either want a C<@PluginBundle>, or L<<
C<PluginLoader::Configurable>
|Dist::Zilla::Role::PluginLoader::Configurable
>>

=head2 WHEN YOU WANT THIS MODULE

=over 4

=item * You don't want a plugin bundle

=item * You want something harder to understand for people who use your plugin.

=item * You B<I<EXPRESSLY>> wish to hide the loaded modules from things like L<<
C<Dist::Zilla::App::Command::bakeini>
|Dist::Zilla::App::Command::bakeini
>>

=item * You are loading a single, or handful of modules, all of which are I<BLATANTLY> obvious I<DIRECTLY> in C<dist.ini>,
except with some special loading semantics.

=back

=head2 ADVICE

=over 4

=item * Do make consuming plugins have to declare the loaded plugin somehow

=item * Do make consuming plugins able to directly configure the loaded plugin somehow

=item * If at all possible, load at most, one plugin.

=item * If at all possible, and you are loading only one plugin, use L<<
C<PluginLoader::Configurable>
|Dist::Zilla::Role::PluginLoader::Configurable
>>

=item * If you have read this far, and you still are considering using this Role, please contact me, C<kentnl> on
C<#[e-mail]>, and let me convince you not to.
