ap/hplip-3.20.5-x86_64-3.txz:  Rebuilt.
  Switched to hplip-3.20.5 to fix regressions in the hp-plugin subsystem.
  Patched to use is_alive() rather than the deprecated isAlive().
  Thanks to Andypoo.
  Newer versions than 3.20.6 require avahi. We'll stick with this version
  for now and leave the decision about whether we love HP more than we hate
  avahi for another day.
