[MITgcm-support] clever pickup too clever for me

[Patrick Heimbach]

Hi Matt,

what has changed is that you now
also provide the .meta file, and its content is checked for consistency
(might be important for seaice where it's not clear which options/ 
grids etc you're using).
Previously, the .meta files weren't evaluated.
If you have an old pickup and didn't keep the .meta file,
then just add in file data under PARM03 following option (as you did)
   pickupStrictlyMatch=.FALSE.,
In that case the model warns you that the pickup might not be  
consistent,
but continues running (assuming you know what you're doing).
So ideally, keep the .meta files for your new runs and provide them
when re-starting from pickup.

-p.
