# Being new to NixOS, I don't understand everything below. I culled and modified it from...
#    https://github.com/NixOS/nixpkgs/blob/master/pkgs/applications/networking/browsers/chromium/default.nix
# which integrates pdfium as its PDF viewer.
#
# Currently `nix-shell` then `unpackPhase` produces an error "unpacker produced multiple directories"
# Reading around, it seemed that uncommenting the #unpackPhase= group might avoid that error, but no dice.
# Looking for some assistance to unpack the tarball.
