The difference here is that nmerge now includes the full source code, released under the GPL v3, and also contains a single example text that I can give away under the same license. It is the first scene of Shakespeare's King Lear. I have tried to make it as true to the source texts as I can but it's a lot of work getting markup to look like a manuscript. I never realised before how much the tags interfere with that. It's very annoying. Anyway, let me know if there are any mistakes. Or any ideas on how Alpha can be improved. I'm sure there are lots.
Of course it is full of markup hacks, mainly lines split over speeches, but I couldn't fix that without introducing another layer for each MS. I'd prefer using some other technology other than markup for the content but there isn't one yet. Oh well!
