* \c Teuchos::MPIComm is deprecated.
*
* The \c Teuchos::MPITraits class is for use with the \c
* Teuchos::MPIComm class and is supposed to compile whether or not
* Trilinos was built with MPI. If you need to convert directly to MPI
* types (e.g., MPI_INT), please refer to Teuchos_MPIRawTraits.hpp.
