I, for one, would very much like to read an article about the preparation of this document and the various tools used in the toolchain, as well as the workflow -- it could serve as a primer for 'how to do ebooks' for the future that I would enjoy greatly.

It looks like Inkscape for the SVG editor, and texinfo for the text, but I know enough to know it would be nice to know what if any special config was done to get the nice fonts, etc.
