[cl-typesetting-devel] How to make some text flush left and some flush right?

[Peter Seibel]

Suppose I want to make a header that has a chapter name on the left  
and a page number on the right like this:

  +--------------------------------------------------------------+
  |   Chapter One                                         p. 1   |
  |                                                              |
  |   Normal text here blah blah blah. The quick brown fox       |
  |   jumps over the lazy dog ...                                |
  |                                                              |

In the past I've built a table but that requires knowing the width of  
the page and computing the width of various pieces of text. It seems  
like there ought to be a simple way to say, make a box containing  
"Chapter One" that is sized to it's natural size, another box  
containing nothing that expands to fill available space, and a third  
containing "p. 1", also sized to it's natural size and then lay those  
three boxes out in a horizontal line to get the effect I want. Is  
there any easy way to do that?
