=head1 SYNOPSIS

    get '/foo/:name' => sub {
        $tokens = shift;
        $etcd = etcd('foo');
        $name = param('name');
        $tokens->{name} = $etcd->range({ key => $name })->get_value;
        [ ... ]
    };

    # save development configs to etcd
    shepherd put

    # retrieve latest version of configs
    shepherd get

=head1 DESCRIPTION

The C<etcd> keyword which is exported by this plugin allows you to 
connect directly to etcd v3 api.

=head1 shepherd

By far the most interesting part of this module is shepherd. shepherd
allows you to save Dancer App YAML configs to etcd by line as key/value.
Even more interesting is that it maintains your comments.  An example of
usage would be spawning a container with the application then simply running
shepherd get --env=production would bring in the latest production configs for
your app.
