[NTG-context] Letter module - appendices

Hi, I know at least a few people use my letter module and I want to ask them if they have a problem when I change the handling of appendices like CC and postscript. The current way to write them is \startletter [copy=..., postscript=...] ... \stopletter and I want to change this in \startletter ... \CC{...} % or \copy{...} \PS{...} % or \postscript{...} \stopletter As positive side effect of the new method would be to write \startletter \opening{...} ... \closing{...} \stopletter as a alternative way to write the opening and closing text (the old keyval works too) but the appendices can be only handled in one way.
