Conventions:
  - The parameter is the ZFS dataset path
  - Every ZFS dataset contains the directories: data, ncmls, catalogs

NcML generation:

for d in $( find /oceano/gmeteo/WORK/zequi/DATASETS/cmip5-esm-subset/data -maxdepth 5 -mindepth 5 -type d ); do find $d -type f | python ncml.py --dataset "/oceano/gmeteo/WORK/zequi/DATASETS/cmip5-esm-subset/"; done

Catalog generation:

python catalog.py --dataset /oceano/gmeteo/WORK/zequi/DATASETS/cmip5-esm-subset
