Hi

When I’ve installed SWI-Prolog on my Ubuntu system yesterday, from the PPA, it showed that there is no more swi-prolog-doc package, even though it is referenced by the swi-prolog package. The documentation seems to be in the swi-prolog-nox package now. So could you please remove the reference to swi-prolog-doc from swi-prolog?

Cheers,  
Volker

Thanks for spotting. May also consider re-adding the doc package. Not really sure why this happened. Possibly a bit too enthusiastic editing when moving to CMake 😢
