This can now be build using a docker container.

Very nice, thank you. I like the comments in the new scripts, thank you.

Adding the rest2www tar file is a good idea I think.

The tarball and other binaries are currently hosted on mag.soton.ac.uk and we need to migrate them to a new place (which?).

I have added one comment to add that this repo does not contain the documentation, but just the high level webpage overview. (Documentaino is in http://github.com/fangohr/nmag-doc, and [somehow] rendered to http://nmag.readthedocs.io.

Can you update the documentation links to point to http://nmag.readthedocs.io?

Regarding making this compile in a container, this looks good to me.

I've changed the links so that they point to http://nmag.readthedocs.io, and I've removed the links for the manual in "multiple html files" because they no longer makes sense.

Looks good to me, thanks.
