The setup script also calls set_extrn_mdl_params.py, sets the GRID_GEN_METHOD with HALO, checks various parameters, and generates shell scripts. Then, the workflow generation script sets up YAML-compliant strings and generates the actual Rocoto workflow XML file from the template file (fill_jinja_template.py). The workflow generation script checks the crontab file and, if applicable, copies certain fix files to the experiment directory. Then, it copies templates of various input files to the experiment directory and sets parameters for the input.nml file. Finally, it generates the workflow.

-This utility fills in a user-supplied Jinja template from either a YAML file, or
-command line arguments.
-
-The user configuration file and commandline arguments should be YAML-formatted.
-This script will support a single- or two-level YAML config file. For example:
-
-    1. expt1:
-         date_first_cycl: !datetime 2019043000
-         date_last_cycl: !datetime 2019050100
-         cycl_freq: !!str 12:00:00
-
-       expt2:
-         date_first_cycl: !datetime 2019061012
-         date_last_cycl: !datetime 2019061212
-         cycl_freq: !!str 12:00:00
-
-    2. date_first_cycl: !datetime 2019043000
-       date_last_cycl: !datetime 2019050100
-       cycl_freq: !!str 12:00:00
-
-    In Case 1, provide the name of the file and the section title, e.g. expt2,
-    to the -c command line argument. Only provide the name of the file in -c
-    option if it's configured as in Case 2 above.
-
-
-Supported YAML Tags:
-
-    The script supports additional YAML configuration tags.
-
-    !datetime      Converts an input string formatted as YYYYMMDDHH[mm[ss]] to a
-                   Python datetime object
-    !join          Uses os.path.join to join a list as a path.
-
-Expected behavior:
-
-    - The template file is required. Script fails if not provided.
-    - Command line arguments in the -u setting override the -c settings.
