The procedure I have been using to update the doc sections is this:
First cvs export -r oacs-4-6-3-final openacs-4 to a temporary directory.
Then I cp acs-core-docs /web/openacs.org/www/doc/opeancs-4-6-3.
Finally I add a link in /web/openacs.org/www/doc/index.adp to the new documentation.
I think we can improve this process when we get openacs.org running as a branch of the openacs repostiory. We can more easily keep the code base up to date, and the acs-core-docs installed on openacs.org will be the latest version.
Also as part of the release process it might be a good test to update openacs.org with the final release code.
