Is this ready for review?

So I've finally been able to build the pdf-docs without error.

Let's say it's ready for review then.

This looks good. Everything builds here. I do see

Makefile:27: recipe for target 'all-pdf-ja' failed
make[2]: [all-pdf-ja] Error 255 (ignored)
for f in *.tex; do platex -kanji=utf8  $f; done

when building the Japanese pdfs (the two Japanese pdfs are generated and, as far as I can determine, look OK). Perhaps a consequence of my system Japanese lang installation which took some effort to get it to work.

@jhpalmieri (John) add your name if you concur.

I never managed to get the Japanese docs working, so I cannot fully test that either.
