  # NOTE: The upstream README indicates that flex is needed for some features,

  # logic for bison and flex is still present in the build script[2], but no
  # other code seems to depend on it. This situation is susceptible to change
  # though, so it's a good idea to inspect the build scripts periodically.

      Apache Traffic Server is a high-performance web proxy cache that improves
      network efficiency and performance by caching frequently-accessed
      information at the edge of the network. This brings content physically
      closer to end users, while enabling faster delivery and reduced bandwidth
      use. Traffic Server is designed to improve content delivery for
      enterprises, Internet service providers (ISPs), backbone providers, and
      large intranets by maximizing existing and available bandwidth.
