Well, it all works. Now I just have to build an installable package for it. To be honest I don't think many if any people will want to use nmerge. It's too user unfriendly because it has no real user interface. People want a GUI these days, and nmerge is designed to be the Swiss army knife for whatever GUI you might want to put on top of it. Nevertheless I will post it as soon as possible with a GNU type installer and maybe a Windows one if that is not too hard (perhaps using Nullsoft). The main point is that a milestone has been reached: the MVD file format is born. (Hooray!)
After that it will be time to add my own GUI, which is just an updating of the Phaidros wiki which has lain untouched for nearly a year now. It is time to update it with some killer features: e.g. Tree View, which will show the genealogy of a set of versions via a graphical tree which you can configure and regenerate according to taste. I have some other ideas too which can be blended in gradually.
