Yes dtoc has some Python classes for reading the DT and updating it (with a separate 'commit' step). I am not entirely happy with the state of it though. If you want to tidy it up and upstream it, that would be great. If you me some pointers as to what you need, I could try it. I need to get back to the fdtgrep stuff in the next week or do, so the timing is right. Regards, Simon
