Usage: $0 --platform=PLATFORM [OPTIONS] 

OPTIONS
  -h, --help
      show this help guide
  -p, --platform=PLATFORM
      name of machine you are building on
      (e.g. hera | jet | hercules)
  -c, --compiler=COMPILER
      compiler to use; default depends on platform
      (e.g. intel | gnu | cray | gccgfortran)
  --continue
      continue with existing build
  --remove
      removes existing build; overrides --continue
  --clean
      does a "make clean"
  --move
      move binaries to final location.
  --exec-dir=EXEC_DIR
      installation binary directory name ("exec" by default; any name is available)
  --conda-dir=CONDA_DIR
      installation location for miniconda (SRW clone conda subdirectory by default)
  --build-jobs=BUILD_JOBS
      number of build jobs; defaults to 4
  -v, --verbose
      build with verbose output
  --atmos-only
      build the MPAS atmosphere core only, this option assumes you have already built the init_atmosphere_model to create the necessary initial conditions and executables.
  --debug
      build MPAS with debug mode
  --use-papi
      builds version of MPAS using PAPI for timers
  --tau
      builds version of MPAS using TAU hooks for profiling
  --autoclean
      forces a clean of MPAS infrastructure prior to build new core
  --gen-f90
      generates intermediate .f90 files through CPP, and builds with them
  --timer-lib=TIMER_LIB
      selects the timer library interface to be used for profiling the model, options are native, gptl, and tau
  --openmp
      builds and links with OpenMP flags
  --single-precision
      builds with default single-precision real kind.  Default is to use double-precision
