11    At the time of this writing, the OSSE requires MITgcm checkpoint48 to
12    compile and run.  MITgcm can be obtained from
13    <http://mitgcm.org/source_code.html>.  If downloading from the CVS
14    server, use the command
15    
16    cvs co -r 'checkpoint48' MITgcm
17    
18    in order to specify the correct version.  Read the instructions on the
19    the webpage before trying to use the CVS server.
20    
21    The OSSE directory tree can be obtained from the MITgcm CVS repository
22    with the command
23    
24    cvs co MITgcm_contrib/osse
25    
26    The code and its revision history can be browsed at
27    
28    <http://dev.mitgcm.org/cgi-bin/viewcvs.cgi/MITgcm_contrib/osse/>

30    A good place to put the osse directory tree is in MITgcm/verification,
31    where examples and test examples of MITgcm configurations are kept.
