Below is a little error from the build of the mqi package. The messages refer to sections of the main manual using \secref{} in Latex. Is there a way to refer to sections of the main documentation from a package?
One can see the problem also online, here:
https://www.swi-prolog.org/pldoc/doc_for?object=section('packages/mqi.html')
Scroll down to Section 1.3 and check the reference to top level/quickstart, it is not being translated to a link.
