$0 is used to generate the Makefile in the current directory.

Typical invocations are:
 o from "bin":   ../tools/genmake
 o from "verification/expt/code": ../../../tools/genmake
 o from "verification/expt/input": ../../../tools/genmake -mods=../code
 o from a scratch directory: ~/mitgcm/tools/genmake -rootdir=~/mitgcm
   or  ~/mitgcm/tools/genmake -rootdir=~/mitgcm -mods=~/mymods

Packages (collected modules of code)  can be disabled to avoid unnecessary
compilation of unused code. For instance if you know you will not
use GM/Redi, KPP and OBCS and they are appropriate turned-off in the
configuration:
   .../tools/genmake -disable=gmredi,kpp,obcs

If you add some source files you can re-call the previous instance of
genmake with "make makefile".

genmake also reads the file .genmakerc which can be used to configure
options (primarily the command-line options above) for particular experiments.
