Sassiini.xml is a XML file that stores user preferences for the SASSI User Interface. The file is generated when a user launches User Interface for the first time or if the file has been removed from the default path. The file is populated with default values from the SASSI User Interface. The user will modify these values with use of the SASSI User Interface UI and these updated values will be saved in the XML file on normal exit from the SASSI User Interface.
