Usage: "$0" [OPTIONS]
  where [OPTIONS] can be:

    -help | --help | -h | --h
	  Print this help message and exit.

    -oad | --oad
	  Generate a Makefile for an OpenAD built

    -nocat4ad | -dog4ad | -ncad | -dad
	  do not concatenate (cat) source code sent to TAF
	  resulting in compilation of multiple files

    -adoptfile NAME | --adoptfile NAME | -adof NAME | --adof NAME
      -adoptfile=NAME | --adoptfile=NAME | -adof=NAME | --adof=NAME
	  Use "NAME" as the adoptfile.  By default, the file at
	  "tools/adjoint_options/adjoint_oad" (for OpenAD built) or
	  "tools/adjoint_options/adjoint_default" will be used.

    -nooptfile | --nooptfile
      -optfile NAME | --optfile NAME | -of NAME | --of NAME
      -optfile=NAME | --optfile=NAME | -of=NAME | --of=NAME
	  Use "NAME" as the optfile.  By default, an attempt will be
	  made to find an appropriate "standard" optfile in the
	  tools/build_options/ directory.

    -pdepend NAME | --pdepend NAME
      -pdepend=NAME | --pdepend=NAME
	  Get package dependency information from "NAME".

    -pgroups NAME | --pgroups NAME
      -pgroups=NAME | --pgroups=NAME
	  Get the package groups information from "NAME".

    -bash NAME
	  Explicitly specify the Bourne or BASH shell to use

    -make NAME | -m NAME
      --make=NAME | -m=NAME
	  Use "NAME" for the MAKE program. The default is "make" but
	  many platforms, "gmake" is the preferred choice.

    -makefile NAME | -mf NAME
      --makefile=NAME | -mf=NAME
	  Call the makefile "NAME".  The default is "Makefile".

    -makedepend NAME | -md NAME
      --makedepend=NAME | -md=NAME
	  Use "NAME" for the MAKEDEPEND program.

    -rootdir NAME | --rootdir NAME | -rd NAME | --rd NAME
      -rootdir=NAME | --rootdir=NAME | -rd=NAME | --rd=NAME
	  Specify the location of the MITgcm ROOTDIR as "NAME".
	  By default, genamke will try to find the location by
	  looking in parent directories (up to the 5th parent).

    -mods NAME | --mods NAME | -mo NAME | --mo NAME
      -mods=NAME | --mods=NAME | -mo=NAME | --mo=NAME
	  Here, "NAME" specifies a list of directories that are
	  used for additional source code.  Files found in the
	  "mods list" are given preference over files of the same
	  name found elsewhere.

    -disable NAME | --disable NAME
      -disable=NAME | --disable=NAME
	  Here "NAME" specifies a list of packages that we don't
	  want to use.  If this violates package dependencies,
	  genamke will exit with an error message.

    -enable NAME | --enable NAME
      -enable=NAME | --enable=NAME
	  Here "NAME" specifies a list of packages that we wish
	  to specifically enable.  If this violates package
	  dependencies, genamke will exit with an error message.

    -standarddirs NAME | --standarddirs NAME
      -standarddirs=NAME | --standarddirs=NAME
	  Here, "NAME" specifies a list of directories to be
	  used as the "standard" code.

    -fortran NAME | --fortran NAME | -fc NAME | --fc NAME
      -fc=NAME | --fc=NAME
	  Use "NAME" as the fortran compiler.  By default, genmake
	  will search for a working compiler by trying a list of
	  "usual suspects" such as g77, f77, etc.

    -cc NAME | --cc NAME | -cc=NAME | --cc=NAME
	  Use "NAME" as the C compiler.  By default, genmake
	  will search for a working compiler by trying a list of
	  "usual suspects" such as gcc, c89, cc, etc.

    -use_real4 | -use_r4 | -ur4 | --use_real4 | --use_r4 | --ur4
	  Use "real*4" type for _RS variable (#undef REAL4_IS_SLOW)
	  *only* works if CPP_EEOPTIONS.h allows this.

    -ignoretime | -ignore_time | --ignoretime | --ignore_time
	  Ignore all the "wall clock" routines entirely.  This will
	  not in any way hurt the model results -- it simply means
	  that the code that checks how long the model spends in
	  various routines will give junk values.

    -ts | --ts
	  Produce timing information per timestep
    -papis | --papis
	  Produce summary MFlop/s (and IPC) with PAPI per timestep
    -pcls | --pcls
	  Produce summary MFlop/s etc. with PCL per timestep
    -foolad | --foolad
	  Fool the AD code generator
    -papi | --papi
	  Performance analysis with PAPI
    -pcl | --pcl
	  Performance analysis with PCL
    -hpmt | --hpmt
	  Performance analysis with the HPM Toolkit

    -ieee | --ieee
	  use IEEE numerics.  Note that this option *only* works
	  if it is supported by the OPTFILE that is being used.
    -devel | --devel
	  Add additional warning and debugging flags for development
	  (if supported by the OPTFILE); also switch to IEEE numerics.
    -gsl | --gsl
	  Use GSL to control floating point rounding and precision

    -mpi | --mpi
	  Include MPI header files and link to MPI libraries
    -mpi=PATH | --mpi=PATH
	  Include MPI header files and link to MPI libraries using MPI_ROOT
	  set to PATH. i.e. Include files from \$PATH/include, link to libraries
	  from \$PATH/lib and use binaries from \$PATH/bin.

    -omp | --omp
	  Activate OpenMP code + use Compiler option OMPFLAG
    -omp=OMPFLAG | --omp=OMPFLAG
	  Activate OpenMP code + use Compiler option OMPFLAG

    -es | --es | -embed-source | --embed-source
	  Embed a tarball containing the full source code
	  (including the Makefile, etc.) used to build the
	  executable [off by default]

    -ds | --ds
	  Report genmake internal variables status (DUMPSTATE)
	  to file "genmake_state" (for debug purpose)

  While it is most often a single word, the "NAME" variables specified
  above can in many cases be a space-delimited string such as:

    --enable pkg1   --enable 'pkg1 pkg2'   --enable 'pkg1 pkg2 pkg3'
    -mods=dir1   -mods='dir1'   -mods='dir1 dir2 dir3'
    -foptim='-Mvect=cachesize:512000,transform -xtypemap=real:64,double:64,integer:32'

  which, depending upon your shell, may need to be single-quoted.
