We have been looking at asciidoc too, so much so that there are draft patches by Jon and me to build some of the documentation from asciidoc source. Both are in the thread starting at [1]. But we really need to consider reStructuredText too [2]. I think this thread is about figuring out how much we really depend on DocBook. There is a lot of pain in dealing with DocBook, especially as a source format, but also as an intermediate format. If we can produce the end results (html, pdf, man, ...) from the source markup directly, it's a win. > ASCIIDoc has gained quite a strong following.

See some of the other threads. Asciidoc seems to be in maintenance mode. Asciidoctor depends on a ruby environment which is not met with enthusiasm. The HTML output can only be chunked (split to several pages) via the DocBook output. Sphinx is active, doesn't add a lot of new dependencies, and seems to be able to natively output all the end results people have so far said they care about. > Many of the open source projects I am involved with are now using > ASCIIDoctor as the documentation form.

I'm hopeful this holds for any of the lightweight markups. BR, Jani.
