version 0.03

    use Dancer;
    use Dancer::Plugin::Mongo;

    get '/widget/view/:id' => sub {

=head1 DESCRIPTION

Dancer::Plugin::Mongo provides a wrapper around L<MongoDB>. Add the appropriate
configuraton options to your config.yml and then you can access a MongoDB database

To query the database, use the standard MongoDB syntax, described in
L<MongoDB::Collection>.

should be specified as follows:

    plugins:
        Mongo:
            host:
            port:
            username:
            password:
            w:
            wtimeout:
            auto_reconnect:
            auto_connect:
            timeout:
            db_name:
            query_timeout:
