          This optional key is used to specify launch on demand sockets that can be used to let launchd know when
          to run the job. The job must check-in to get a copy of the file descriptors using APIs outlined in
          launch(3).  The keys of the top level Sockets dictionary can be anything. They are meant for the appli-cation application
          cation developer to use to differentiate which descriptors correspond to which application level proto-cols protocols
          cols (e.g. http vs. ftp vs. DNS...).  At check-in time, the value of each Sockets dictionary key will
          be an array of descriptors. Daemon/Agent writers should consider all descriptors of a given key to be
          to be effectively equivalent, even though each file descriptor likely represents a different networking
          protocol which conforms to the criteria specified in the job configuration file.
