  <!--
  The following code sets which sections start new pages in the PDF document flow.
  
  The parameter "boost.section.newpage.depth" set how far down the hierarchy the
  page breaks go.  Defaults to 1 (the same as html chunking), in which case only 
  top level sections start a new page, set to a higher value to force nested sections
  onto new pages as well.
  
  For top level sections (level 1), we use "break-before" which forces the very first
  section onto a separate page from the TOC.
  
  For nested sections (level 2 and greater) we use "break-after" which keeps nested
  sections together with their enclosing section (rationale: the enclosing section
  often has nothing but a title, and no content except the nested sections, and we 
  don't want a page break right after a section title!).
  
  For reference sections, we turn page breaks *off* by setting "refentry.pagebreak" to 0.
  This is for the same reason we use "break-after" for nested sections - we want reference 
  entries to be on the same page as the title and synopsis which encloses them.  Ideally
  we'd use "break-after" here too, but I can't find an easy to to fix that.
  
  Finally note that TOC's and Indexes don't get page breaks forced after them.
  Again there's no easy fix here, *except* for the top level TOC which gets a page break
  after it thanks to the "break-before" on level 1 sections.  Unfortunately this means
  there's no break after the last section and before the first Index, *unless* the
  final section has nested sections which may then trigger one!
  
  We could fix all this by cut-and-pasting the relevant XSL from the stylesheets to here
  and making sure everything uses "break-after", but whether it's worth it is questionable...?
