38  <blockquote>  <pre>
39  Using a Bourne, "bash", or "sh-compatible" shell:    $ export CVSROOT=':pserver:cvsanon@mitgcm.org:/u/gcmpack'
40      $ cvs login
41        ( enter the CVS password: "cvsanon" )
42      $ cvs co -P MITgcm

54        <p>using the "-P" option to check-out ("<i>cvs co -P</i>") prevents
55        to download unnecessary empty directories.</p>
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>
66    
67  <pre>  <pre>
68  $  export CVSROOT=':pserver:cvsanon@mitgcm.org:/usr/local/gcmpack'    $ cvs co -P MITgcm_contrib/submesoscale
 $  cvs login  
 ( enter the CVS password: "cvsanon" )  
 $  cvs co MITgcm MITgcm_contrib
