56        
57        <p>A large amount of additional (optional!) content is available
58        from the <i>MITgcm_contrib</i> directory; much of it is specific to certain
59        setups (eg. high-res setups, in-development material that is not yet part
60        of the "main" code, etc ...).
61        But rather than checking out the full content of MITgcm_contrib
62        ("<i>cvs co -P MITgcm_contrib</i>"), which takes a long time to download
63        (particularly from remote locations), we recommend to download only the
64        specific part of interest, e.g.: "<i>submesoscale</i>" directory,
65        which can be checked out using:</p>

76        <p>Also note that it is possible to checkout code without "cvs login" and
