Forum OpenACS Q&A: Re: How to integrate an existing category with other package?

I found out that the information in the tutorial is  ambiguous and I could only make it work on a HEAD installation. Well, I could at least make this one work: https://openacs.org/doc/openacs-5-1/ch10s06.html

There are actually two documents about categories in the tutorial: https://openacs.org/doc/openacs-5-1/acs-package-dev.html

Hope this helps.
