  59 # http://askubuntu.com/questions/3503/best-way-to-cache-apt-downloads-on-a-lan
  60 # apt-cacher-ng doesn't have zeroconf.
  61 # so I'm not sure how smart it will be if the server goes down.
  62 # It touts having minimal dependencies, but I don't care.
  63 # The downside to squid-deb-proxy is that it's config is for specific repos,
  64 # you have to add all the repos you use.
  65 # That is the main reason I use apt-cacher-ng.
