如何创建一个包裹所有其他子div的子div

Question

I have this html structure:

<div class="a">
    <div class="b"></div>
    <div class="c"></div>
    <div class="d"></div>
</div>

How can would I use jquery to add child div to div "a" that would wrap around "b", "c" and "d"? Basically, the final html I want should look like this:

<div class="a">
    <div class="child">
        <div class="b"></div>
        <div class="c"></div>
        <div class="d"></div>
    </div>
</div>

Thanks
