A simply newbie question about ndiff

[Neville Franks]

Hi David,
Ok this all starts to make some sense now. I did see some docs refer to
ndiff being in difflib but then other difflib doc's which didn't mention it.
I did try executing '/tools/scripts/ndiff' but have to admit I don't really
know what I'm doing just yet and didn't get anywhere. Is there some one to
run this in 2.1.2 or should I just install 2.2?

Thanks for your help.
