I have a reference document for some software that I would like to publish online, and to provide a pdf and multi-page html version. DocBook looks idea for this, similar to how subversion publish their manual; http://svnbook.red-bean.com/
However I would like to be able to collaboratively edit the document on the similar to google docs, or mediawiki.
I am using lots of equations so LaTax support is highly sought after.
Any suggestions on what I can use?
I have looked at the Heirarchy and DocBook plugins for wikipedia, but they seem old and unmaintained and I couldn't get them to work as I want.
