intro

    Frotz is an interpreter for the games produced by Infocom, Inc., which were
    released in a machine-independent format. On all platforms the games were
    released as a data file plus an interpreter, so this program can be used to
    play Infocom games released for any platform. Frotz is the fastest and most
    accurate Infocom interpreter currently available for the Amiga. Kickstart
    2.04 or higher is required.

    Infocom's games can be grouped into several basic formats, each descended
    from the previous one. These are:

    	v1 and v2		The earliest games, released in 1979-80.

    	v3			Most Infocom games were in this format,
    				from Zork 1 to Stationfall.

    	v4			Designed for the then new 16 bit micros,
    				v4 games were much larger than v3 games.
    				Trinity, A Mind Forever Voyaging,
    				Bureaucracy and Nord & Bert were released
    				in this format.

    	v5			The format was extended again for
    				Beyond Zork, Border Zone and Sherlock.

    	v6			The last, "graphic" games: Arthur,
    				Journey, Shogun and Zork Zero.

    Since Infocom ceased to exist there has been much effort put into under-
    standing the Infocom format, and the compiler Inform has been written by
    Graham Nelson which can produce adventure games in this format. Later
    releases of Inform have introduced two new formats, allowing for even larger
    games. These are v7 and v8, and such games can also be interpreted by Frotz.
    For more information, see the IF Archive. Frotz conforms to the Z-Machine
    Standard 1.0, which defines exactly the required behaviour of an Infocom
    interpreter.
