#
#   1. In any directory, create 'Tables/', 'Test/' and 'CMIP6/' directories.
#
#   2. Download
#      https://github.com/PCMDI/cmor/blob/master/TestTables/CMIP6_Omon.json
#      and https://github.com/PCMDI/cmor/blob/master/TestTables/CMIP6_CV.json
#      to the 'Tables/' directory.
#
#   3. Download
#      https://github.com/PCMDI/cmor/blob/master/Test/<filename>.json
#      to the 'Test/' directory.
