Which platforms does Trinity support?

The Welcome help handbook says the following: TDE is a graphical desktop environment for UNIX® workstations. The Trinity Desktop Environment combines ease of use, contemporary functionality, and professional graphical design along with the technical advantages of the UNIX® operating system. The underlying KDE3 source code supported many Unix-like Operating systems. Are we still supporting anything other than Linux based systems? I want to make the handbook statement technically correct. "Unix and Unix-like" systems? "Unix, Unix-like, and Linux based" systems? Darrell
