[MITgcm-devel] tags and TAMC-compatibility

[Jean-Michel Campin]

Hi Dimitris,

I don't know if my problem with advection scheme 7 is related to yours,
but I can check-in a fix, and then you could try again, to see if it
works better. I already run the 3 advections test cases, and it has
only very little effects, so that it seems right to me.
Cheers,
Jean-Michel
