:
* Git;
* Lightweight markup languages;
* Static Site Generators;
* Continuous Integration;
* Hosted Documentation Services;
The issues with that approach are:
* How are screenshots integrated into the documentation?
* How do users find that documentation?
* Documentation is no longer available offline;
That said, I can see a place for adopting a process along those lines,
in creating documentation for extensions, templates, and specific How-Tos.
