Joomla extensions for documentation

I need an extension for Joomla 1.5 or 2.6 that will provide me good processes for implementing and managing an internal online documentation system. The system should have version control\release history, nested categorization, allow embedded documents and searching of tags

Does an extension like the above exist?

I would appreociate suggestions. All my searches haven't come up with anything yet. DOCman seems to be be a physical document reposistory rather than allowing online documentation management.
