ogmmerge
ogmtools is an outdated old program, *but* it comes with dvdxchap which is golden (and I now have a replacement, dvd_info can output OGM chapter format).
archives: ogmmerge notes
including chapters
It seems to only work IF you do -c argument first
Known working:
ogmmerge -o steve.ogm -c @chapters.txt steve.avi
