A.Buchanan: Gunter what do you mean by Antiphoenix, please? Seems just 2xPhoenix to me… (2023-08-07)
Joost de Heer: Antiphoenix is a deprecated keyword and should not be used anymore. (2023-08-07)
A.Buchanan: I completely agree Joost, but it clearly means something to Gunter who uses it from time to time, and I would like to understand him (2023-08-07)
