I thought the experiment directories were created when the setup script is run, so any changes should be to the script rather than the directories themselves?

This is to save the settings of the experiment directory that is being used for the realtime experiment. For instance, we want to save a copy of the XMLs that are being run since it is the only place they exist. You may also have changes in the configuration files that are different than what are under parm/config/gfs.

Having said that, this experiment directory was created from the gsl_ufs_dev branch before we made changes to the configuration files in gsl_ufs_rt, so we should wait to commit this directory until after we update the version of UFS so we get the updated files.

Ka Yee, we will also need to add the XML files in the realtime directory, including the PyGraf ones.
