 #  It fixes the ' \' versus ' &' terminator ;  
 #  with older versions (v4.0): namelist problems with syntax such as:  
 #     fields(1,1) = 'UVELSLT ','VVELSLT ','WVELSLT ',  
 #      which results in run-time errors.)

13    # run with OpenMP: needs to set environment var. OMP_NUM_THREADS
14    #    and generally, needs to increase the thread stack-size:
15    #   -  sh,bash:
16    #     > export OMP_NUM_THREADS=2
17    #     > export GOMP_STACKSIZE=400m
18    #   - csh,tcsh:
19    #     > setenv OMP_NUM_THREADS 2
20    #     > setenv GOMP_STACKSIZE 400m
