class Survey(CMakePackage):
    """Survey is a high level performance tool product from Trenza, Inc.
       The survey collector/analytics framework is a new generation,
       high level, lightweight multiplatform Linux tool set that
       targets metric collection for high level performance analysis
       of applications running on both single node and on large scale
       platforms, including the Cray platforms.

       The collector is designed to work on sequential, MPI, OpenMP,
       and hybrid codes and directly leverages several interfaces
       available for tools inside current MPI implementations including:
       MPICH, MVAPICH, MPT, and OpenMPI. It also supports multiple
       architectures and has been tested on machines based on Intel,
       AMD, ARM, and IBM P8/9 processors and integrated GPUs.

       Survey is a licensed product with the source not openly available.
       To access the survey source and build with spack please contact:
       Trenza Inc. via: dmont@trenzasynergy.com or
