Use jQuery's .wrap on all children of a given tag

Working jQuery, what I'd like to perform is something similar to the following: ``` $('sometag').children().wrap('<div></div>'); ``` With the resulting DOM manipulation wrapping all children in one div, not each child individually. Starting example HTML: ``` <div> <h3>Heading</h3> <p>Paragraph</p> </div> ``` What this line of code does: ``` <div> <div> <h3>Heading</h3> </div> <div> <p>Paragraph</p> </div> </div> ``` What I want: ``` <div> <div> <h3>Heading</h3> <p>Paragraph</p> </div> </div> ``` What is the proper syntax to achieve the end result I'm looking for?
