 -writableRoot       store runtime game data in root data directory
                       (only use if you have write permissions on that directory)
 -ooslog             dumps simulation state in binary and ASCII representations each turn,
                       files created in sim_log within the game's log folder. NOTE: game will
                       run much slower with this option!
+-ooslog-unique      adds unix timestamp and process id to the filename of the out of sync log
+                     to prevent the file from being overwritten by another process.
 -serializationtest  checks simulation state each turn for serialization errors; on test
                       failure, error is displayed and logs created in oos_log within the
                       game's log folder. NOTE: game will run much slower with this option!
