/** @namespace ush
@brief Utility scripts for testing and workflow management.

The ush directory is the resting place of most of the Python scripts
in the HWRF package, but it also contains a number of simple utility
scripts for testing the hwrf or produtil packages, or for managing the
HWRF workflow.

Utility scripts of general interest:

* setup_hurricane --- this is the script run by the NOAA Senior Duty
  Meteorologist (SDM) every six hours to create message files input to
  the HWRF and GFDL hurricane models.

* psychoanalyst --- checks the HWRF installation to see if it is
  complete.  This runs the same checks done by the Rocoto run_hwrf.py
  script, but does not actually launch any jobs.

* hwrf_scrub --- called from the Rocoto workflow scrubber jobs to
  delete directory trees and log relevant messages.  It includes
  safeguards to prevent accidental deletion of important directories
  like / and $HOMEhwrf

* hwrf_deliver --- a wrapper around produtil.datastore.deliver_file()
  which provides most of its functionality.

* hwrf_datastore --- query or manipulate an HWRF database file

* hwrf_completion --- run by the Rocoto completion job to log
  completion of an HWRF forecast cycle.

* hwrf_stream_parse --- a wrapper around produtil.atparse.AtParser,
  this is a simple preparser, which replaces the Perl script of the
  same name in the old ksh-based system.

* rocoto_from_vitals --- generate Rocoto cycle definitions from
  tcvitals files.
