1.3       aaron      45: .Nm

        !            47: .Nm machine
        !            48: command displays the machine's architecture in slightly different ways.
        !            49: .Nm
        !            50: by default displays the application architecture, defined by both the
        !            51: operating system and the instruction set architecture, while
        !            52: .Nm machine
        !            53: displays the kernel architecture (without the operating system part).
        !            54: Note that both commands output the target architecture as opposed to
        !            55: .Xr uname 1
        !            56: which describes the host.  This is useful for dynamic discovery
        !            57: of the target architecture in build or configuration scripts
        !            58: needing to work in cross-compilation environments.

                     64: Display the kernel architecture instead of application
                     65: architecture.
1.4     ! niklas     66: .It Fl s
        !            67: Display the chosen architecture in a short form, i.e. without the
