[MITgcm-support] [MITgcm Manual] section 3.2 Obtaining the code

[jeff polton]

Ed, downloading the checkpoint file with wget seemed to give me 
something better than I had before.... (or is it just me?!). Anyway, it 
compiles nicely now and I even figured out how to use a pgf90 compiler 
(option file given below).
Cheers,

Jeff
