The package provides

• \grabbox<*>[<prepre>]{<register>}[<pre>]{<mode>}[<post>]{<next>}: grab the next argument as a box in <mode> (\hbox, \vbox or \vtop) and save it in box <register>. After the box is saved execute <next>. Inside of the box one can inject <prepre> and <pre> before the contents and <post> after them. If the star is not given spaces are stripped from the start and the end of the box.
