+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.
