# For some reason, the main binary tarballs don't include the .desktop file or
# icon. The .deb does. One would hope then, that we could just download the .deb
# for each arch, but they only generate a .deb for amd64. Maybe we can get them
# to fix this, but in the meantime, we download the .deb purely to get the
# .desktop file and app icon out of it.
