The managing of OpenACS documentation has evolved a few different ways. Instead of working on a unified consensus in managing the OpenACS documentation, there are primarily three efforts:
Approach 0: Continue updating docbook documentation via CVS (for those with access to CVS).
Approach 3: en:New_Documentation_Process is migrating the original OpenACS docbook docs to an xowiki instance.
Approach 4: en:Documentation_Project_Plan is building new documentation based on how the brain likes to chunk using subsystems.
See en:Documentation_Project_Discussion for current status.
