E-book versions

[rvosa]

It would be good to have somewhat better releases for the next version. E.g.:

• make a PDF version and tag that as "the" release DOI
• attach other e-book versions and the source tree as dependent DOIs (you can do this in zenodo)

This way the DOI actually links to something useful for readers rather than the zipped repository, and we are in control of the PDF and e-book versions (rather than have these be dispersed by 3rd parties), so we can track downloads and such.

I can only agree.
