J-M I saw your checkpoint37. I made a branch "pre38": cvs tag -b pre38 Until the next checkpoint we're all supposed to be working in that branch: cvs co -d pre38 -r pre38 -P models/MITgcmUV There's also a file called doc/ChangeLog.pre38 which we edit as we go... I'm in bed with the flu so that's all I'm doing today. A.
