Please mention in the help file the defaults for command line mode, and what do they mean.
I'm not sure if the other modes have defaults, but in Sync mode this means "readonly daylightsavings timestamps attributes".
It's especially confusing as the GUI phrases 2 of them in a negative manner ("ignore X").
I have no way to know if, say, "readonly" is compatible to the GUI or does it actually mean DO include read-only files. Maybe it should have been called "no-readonly" and "no-daylightsavings".
