extern NSString *const TFOptionFlushSecondsInterval; // Defaults to @60. Set to a number. @0 turns off the flush timer. 30 seconds is the minimum flush interval.
extern NSString *const TFOptionLogOnCheckpoint; // Defaults to @YES. Because logging is synchronous, if you have a high preformance app, you might want to turn this off.
extern NSString *const TFOptionLogToConsole; // Defaults to @YES. Prints remote logs to Apple System Log.
extern NSString *const TFOptionLogToSTDERR; // Defaults to @YES. Sends remote logs to STDERR when debugger is attached.
extern NSString *const TFOptionReinstallCrashHandlers; // If set to @YES: Reinstalls crash handlers, to be used if a third party library installs crash handlers overtop of the TestFlight Crash Handlers.
extern NSString *const TFOptionReportCrashes; // Defaults to @YES. If set to @NO, crash handlers are never installed. Must be set **before** calling `takeOff:`.

If they are away from the app for longer, a new session is created when they come back. Must be a number. Change to @0 to turn off.
