          notifier - cups notification interface

          notifier recipient [ user-data ]

          The CUPS notifier interface provides a standard method for
          adding support for new event notification methods to CUPS.
          Each notifier delivers one or more IPP events from the stan-
          dard input to the specified recipient.

          Notifiers MUST read IPP messages from the standard input
          using the ippNew() and ippReadFile() functions and exit on
          error.  Notifiers are encouraged to exit after a suitable
          period of inactivity, however they may exit after reading
          the first message or stay running until an error is seen.
          Notifiers inherit the environment and can use the logging
          mechanism documented in filter(7).
