# IFP header definitions for Nitfol 0.5.
#
# The Z-machine game file format, as it stands, doesn't really lend
# itself to recognition - see the file /usr/share/misc/magic, or equi-
# valent, for evidence of this.  However, for us, what matters most is
# differentiating Z-machine games from other IF games, not from all
# other files.  Here we're looking for the first byte be 0x01 to 0x08
# (the version number), and the second be 0x00-0x0F (Z-machine uses
# only low nibble "flags", so far, anyway).  Moreover, we need to make
# a small gap in this recognition space for Alan, which uses the first
# two bytes as its game version - currently 2.7 or 2.8.  It turn out
# that we can just about get away with this, since the only games known
# to use Z-machine version 2 are older Zork I and Zork II, and for
# these particular two games, "flags" is known to be 0x00.  So until,
# Alan goes to version 3, we're okay.

"Nitfol is a portable interpreter for Z-machine code, the game format
 used by Infocom and more recently, Inform
 (http://www.gnelson.demon.co.uk/inform.html).  Nitfol handles versions one
 through eight of the format, and attempts to comply with version 1.0 of
 the Z-machine specification.\n"
