The Deprecated keyword is just misnamed, I believe it does the same thing as
Ignore, except that it also prints a warning that the switch is no longer
supported, so kind like Ignore Warn(switch %<-frepo%> is no longer supported).
The description should be just This switch has no effect. or
Does nothing.  Preserved for backward compatibility.
