+Usage: "$0" [OPTIONS]
+  where [OPTIONS] can be:
+
+    -help | --help | -h | --h
+          Print this help message and exit.
+
+    -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".
+
+    -pdefault NAME | --pdefault NAME
+      -pdefault=NAME | --pdefault=NAME
+          Get the default package list from "NAME".
+
+    -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".
+
+    -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.
+
+    -[no]ieee | --[no]ieee
+          Do or don't use IEEE numerics.  Note that this option 
+          *only* works if it is supported by the OPTFILE that 
+          is being used.
+
+  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.
