[MITgcm-support] MIT with OpenAD

[andrey.vlasenko]

   Dear Partick and Jean,

   I probably confused you with my request in last e-mail. Currently I 
have already installed and working OpenAD. As Abhisek, I need some 
pointers on how to connect OpenAD to *MITgcm*. I would be very grateful 
to you, if you send it to me.

   With best regards,

   Andrey.
