	# Splitting
	# We currently have to use genbookOsis2Commentary (since
	# osis2mod doesn't accept format unless it is marked up like a Bible),
	# genbookOsis2Commentary is a quick hack, and doesn't work well
	# with big files, since it is DOM based.  So we split the file
	# into lots of small ones, using markers inserted before.
	# Then recombine again.  This is hacky, should go away once
	# osis2mod is fixed.
