that it
   doesn't <em>need</em> to be done, because notangle and noweave can accept
   multiple files on the command line.)  The long answer is that you
   can usually use LaTeX's \include or \input commands and keep the
   noweb files separate.  If you actually need to tangle all those
   files together (as opposed to just weaving them), you can usually
   mention all the names on the command line: 
<pre>
      notangle foo.nw bar.nw quux.nw > big.out
</pre>
