Control: tags + unreproducible Dear Alan,
Thanks for your report. Unifortunately, I have no idea why you faced the bug you reported. These two directories /usr/share/doc/swi-prolog-doc/{Manual,packages} is in fact a symlink to ../../swi-prolog/doc/{Manual,packages}. If you download, say, swi-prolog-doc_8.2.4+dfsg-1_all.deb and navigate through it with the help of, say, mc, you'll see that everything is in the correct place and symlinks are properly created. I'd like to stress that apt-file doesn't show symlinks properly and so reports /usr/share/swi-prolog/doc/Manual as an empty directory. My guess is that you faced a kind of race condition while updating doc-base or improper work of dpkg/apt/whatever installs packages on your machine. Regards, Lev Lamberov
