Hey Dominic,

I'd love to roll the patches in. Unfortunately, they don't apply to trunk, and it'd be a fair amount of work to get them into shape to apply to trunk (it's mainly whitespace differences best I can tell). If someone was able to port it, though, I'd be more than happy to see them applied.

Cheers,

Aaron

Hi Aaron

Is there any chance that these can be rolled in to trunk?

Thanks

Hi Daniel,

As Alan noted, NDT currently only works with web100, and not web10g. However, Richard Sanger has produced a set of patches for using NDT with web10g. I've cc'd Richard who may know the current state of the patches (I've attached the most recent copies I know of), and which version of NDT they apply to.

Cheers,
Aaron
