[Users] Questions re. CarpetRegrid2

I have a few questions about CarpetRegrid2:

- In doc/, the documentation.tex file, for me, just seems to be a bunch of headers with no text in them. Am I missing something?

- In param.cll, the variable min_distance is described as "Minimum distance (in grid points) between coarse and fine grid boundaries". Which grid points are being counted -- the fine or the coarse ones? I'm guessing it's the coarse.

- Can CarpetRegrid2 be used to (easily) define a "hollow box", that is, a set of (6) slabs which are defined on some rectangular surface and only a certain number of points "thick"?

Thanks! -Scott
