Forum OpenACS Q&A: What is the license of OpenACS documentation?

I am searching the license to the OpenACS documentation, but I haven't can find it in https://openacs.org/doc/. I suposse that OpenACS want allow some rights to the users like freedom to copy or modify?, but if OpenACS don't explicit it (in the international copyright laws) by default all rights is reserved to the holder.

The documentation is GPL since it is distributed
as part of OpenACS which is also GPL. Consequently
people are free to modify it arbitrarily and redistribute
it.
Okz. The GPL is a good license for the documentation. I think that include some reference to this license in my free documents to OpenACS.
