bob_ninja I found reference to at least two when I first looked at this thread (somewhere). I looked at one
http://www.sandroid.org/GutenMark/ which I have mistakenly referred to as Gutenberg Mark.
Having been dealing with Gutenberg texts for a good many years now, I wish I had found it earlier. For many purposes it looks really useful. I will certainly be using it.
I unfortunately did not look at the other software that was mentioned, and now cannot remember them. I will look again at the thread and if I can read the whole thing through (time is scarce) I will try and write a small summary.
But have a look at GutenMark, I have not downloaded it yet, but it seems to do all the most boring bits really well. I cannot say much more until I use it.
