**********************************************************************
* PRE-DEPRECATION WARNING: MPIR Support
*
* As was announced in summer 2017, Open MPI is deprecating support for
* MPIR-based tools beginning with the future release of OMPI v5.0, with
* full removal of that support tentatively planned for OMPI v6.0.
*
* This serves as a pre-deprecation warning to provide tools developers
* with sufficient time to migrate to PMIx. Support for PMIx-based
* tools will be rolled out during the OMPI v4.x series. No runtime
* deprecation warnings will be output during this time.
*
* Runtime deprecation warnings will be output beginning with the OMPI v5.0
* release whenever MPIR-based tools connect to Open MPI's mpirun/mpiexec
* launcher.
