Get systype for FTP-cmd "TYPE"
I'm working on a small FTP-server and I'm now have to implement the "TYPE"- command which return the type of the system (for instance "UNIX L8")... but is there any chance to get type of the system using D? Is there any getSysType()- function? I was unable to find anything like that in Phobos...
