 code: modifications to MITgcm to run in cyclindrical coordinates.  At
 the time of this writing, it requires checkpoint48 to compile and run.
 
+input: initialization and input files for MITgcm
+
 filter: source and data files to run the data assimilation and Kalman
 filter.
 
+utils: assorted Matlab m-files 
+
+EnKF: empty
+
+run: empty

+COMPILING AND RUNNING THE MODEL
+
+The following series of commands creates the MITgcm executable.  
+
+From the MITgcm root:
+
+cd verification/osse
+mkdir build   # directory name is arbitrary  
+cd build
+../../../tools/genmake -mods=../code  # creates makefile
+make depend       # contructs Fortran code from model codebase
+make              # makes executable mitgcmuv
+
+Try a test run, while redirecting the standard output to a file.  The
+input directory contains files that should be present in the working
+directory when you run mitgcmuv.  It is recommended that you copy the
+input contents to a different directory for running -- mitgcmuv does
+not change them, but they can be lost in the multitudes of output
+files.
+
+The data assimilation code is made by typing ``make'' in the filter
+directory.
