I find pdf-tools really slow in comparison to zathura, with very
little benefit to it being integrated into Emacs. Zathura is faster,
leaner and more fit for purpose.
PDFs, if a shell command may be invoked on them in dired, now show
zathura as a default argument.
This is obviously just temporary until I find uses for them again. Of
course, if I do want to use them I can just call the emacs-lisp block
to pull the repository and install it.
