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

OPTIONS
  -h, --help
      show this help guide
  -p, --platform=PLATFORM
      name of machine you are building on
      (e.g. cheyenne | hera | jet | orion | wcoss2)
  -c, --compiler=COMPILER
      compiler to use; default depends on platform
      (e.g. intel | gnu | cray | gccgfortran)
  -a, --app=APPLICATION
      weather model application to build
      (e.g. ATM | ATMW | S2S | S2SW)
  --ccpp="CCPP_SUITE1,CCPP_SUITE2..."
      CCPP suites (CCPP_SUITES) to include in build; delimited with ','
  --enable-options="OPTION1,OPTION2,..."
      enable ufs-weather-model options; delimited with ','
      (e.g. 32BIT | INLINE_POST | UFS_GOCART | MOM6 | CICE6 | WW3 | CMEPS)
  --disable-options="OPTION1,OPTION2,..."
      disable ufs-weather-model options; delimited with ','
      (e.g. 32BIT | INLINE_POST | UFS_GOCART | MOM6 | CICE6 | WW3 | CMEPS)
  --continue
      continue with existing build
  --remove
      removes existing build; overrides --continue
  --clean
      does a "make clean"
  --build
      does a "make" (build only)
  --build-dir=BUILD_DIR
      build directory
  --install-dir=INSTALL_DIR
      installation prefix
  --bin-dir=BIN_DIR
      installation binary directory name ("exec" by default; any name is available)
  --build-type=BUILD_TYPE
      build type; defaults to RELEASE
      (e.g. DEBUG | RELEASE | RELWITHDEBINFO)
  --build-jobs=BUILD_JOBS
      number of build jobs; defaults to 4
  --use-sub-modules
      Use sub-component modules instead of top-level level SRW modules
  -v, --verbose
      build with verbose output

TARGETS
   default = builds the default list of apps (also not passing any target does the same)
   all = builds all apps
   Or any combinations of (ufs, ufs_utils, upp, gsi, rrfs_utils)
