Pod wrong

Hi,

Your SYNOPSIS shows:

```perl
my $app = sub {
    return [
        200,
        [ 'Content-Type' => 'text/html' ],
        [ "<title>Hello!</title><h1>Hello</h1>\n<p>World!</p>" ]
    ];
};
```

I _think_ you mean:
```perl
my $app = sub {
    return [
        200,
        [ 'Content-Type' => 'text/html' ],
        [ "<head><title>Hello!</title></head><body><h1>Hello</h1>\n<p>World!</p></body>" ]
    ];
};
```

Haven't had time to play just thought I'd mention it
