=======================================

To apply the changes to the default configuration of MITgcmUV:
  mkdir bin exe
  cd bin
  ln -s ../verification/exp2/code/SIZE.h ../bin/
  ln -s ../verification/exp2/code/CPP_OPTIONS.h ../bin/
  ln -s ../verification/exp2/code/CPP_EEOPTIONS.h ../bin/

Configure and compile the code:
  cd ../bin
  ../tools/genmake -makefile
  make depend
  make

To run:
  cd ../exe
  cp ../verification/exp2/input/* .
  mitgcmuv >&! output.txt

There is comparison output in two directories:
 ../verification/exp2/results/output.txt

Comments:
The input data is real*4.
