Let's say you want the list of files in the current work directory. While  
system("dir") will execute the command it is obviously useless. With  
boost::process::shell("dir") you can read the list of files through a  
stream though. In a way boost::process::shell() is nothing more than a  
convenient shortcut for boost::process::create_child("cmd.exe"...).
