SmartSVN supports a couple of command line arguments.
--server-modewill just start up the core process and bring up the tray icon , if present. This startup mode is used for the Shell Integration .
--exitwill try to detect a running SmartSVN process and force this process to exit. This allows to stop SmartSVN programmatically.
--transactionswill bring up the Transactions Frame instead of the Project Window on startup.
--repository-browserwill bring up the Repository Browser instead of the Project Window on startup.
