While I'm impressed with this news.

I'm pretty sure xmlto doesn't depend on dblatex and/or texlive.

I'm building Git and Git's documentation on different Linux boxes with
asciidoc, most of them don't have dblatex and/or texlive.
In fact, I only have texlive installed in my laptop.

I guess you're using Debian or one of its derived distribution?
Debian puts dblatex as xmlto's rec. [2]

I think you can use:

	apt install --no-install-recommends xmlto

to avoid those recommendations.

Hm, I'm pretty sure Ruby (asciidoctor's language) is very hard to port.
Last I heard, it's buggy on some platforms.

I think we're better to do like this:

* If we're using asciidoc, we will use xmlto
* If we're using asciidoctor, we will generate man-pages with
  asciidoctor directly
