The run.properties file was produced in the past purely for use in providing information to downstream data consumers like CERA and StormSurgeViz. This file has steadily increased in importance, and has become the preferred solution to long lists of command line arguments for various subsystems. This milestone marks the transition to an operating paradigm where the ASGS starts setting up a run by creating the associated run.properties files. Then the various subsystems (for example, the fort.15 file creation script, the post processing, etc) all read the run.properties files to figure out what to do for that job. This milestone must also include reasonable defaults for each piece of metadata, the inclusion of all the metadata into the netcdf output files, and official documentation of all metadata for use by downstream data consumers.
