It appears that the key is in this file.  This file *must* have
a headline of level 1 or nothing else works.  Who knew?  (Except
Carsten, of course)  :)

Your example doesn't show this as both have level 2 trees, but, yes,
if the main file has a level 1 headline *before* including any further
files then the structure is honored.

This is a little awkward but not too bad.

Yeah, I am using a custom org-export-latex-classes so I can use memoir
and do some further customizations.

I am going to play around with this.  I looked at the code for the latex
exporting and had trouble following it (I am not a lisp expert by any
means).

Thanks for discovering this.  I would not have tried this as I am
keeping different kinds of information in different files and simply
using a 'main' file to group them for 'pretty-printing'.  It's not
really a book.  It is my notes of ongoing tasks for my team that I use
for my 'Management by Walking Around' style... :)  One chapter is for
ongoing tasks, one chapter for bugs, one chapter for project schedule
items, etc.  They are short chapters but having it all collected
simplifies my life when I go into meetings and need to report on the
progress of any particular item.
