This is nice to test/build a single document, only issue is that it won't use our template/css.
Just to know, these html's will be used where?

Seems fine.

I think for now is better skip pdf for articles/pgpkeys, it seems the issue is not the includes but its content.

One other note: the pgpkeys article takes about two hours to build on my (admittedly single-CPU 2GB RAM) machine - is that common and do we need to work around that somehow?

Small style fixes.

Built docs are now saved in matching public/lang/articles|books/ directory. Clean targets updated as well.

Seems fine IMHO.

• Switch to other theme to allow CJK and other fonts to be embedded. Our default theme is less good than the one provided by asciidoctor-pdf.
• Updates with Ceri's comments. I still have to save the pdf to a better suited directory.
