That sounds fine, but I would like to see stage 1 and stage 3 be
as close as possible.  In other words, the less work is required
to go from stage 1 to stage 3, the better.  That way, the author
is encouraged to do the work from the beginning because it's easy,
and we don't have any line that we cross that makes it hard for
the author to edit the document, e.g. if errata are reported.
