# MacBinary format (Eric Fischer, [e-mail])
#
# Unfortunately MacBinary doesn't really have a magic number prior
# to the MacBinary III format.  The checksum is really the way to
# do it, but the magic file format isn't up to the challenge.
#
# 0	byte		0
# 1	byte				# filename length
# 2	string				# filename
# 65    string				# file type
# 69	string				# file creator
# 73	byte				# Finder flags
# 74	byte		0
# 75	beshort				# vertical posn in window
# 77	beshort				# horiz posn in window
# 79	beshort				# window or folder ID
# 81    byte				# protected?
# 82	byte		0
# 83	belong				# length of data segment
# 87	belong				# length of resource segment
# 91	belong				# file creation date
# 95	belong				# file modification date
# 99	beshort				# length of comment after resource
# 101	byte				# new Finder flags
# 102	string		mBIN		# (only in MacBinary III)
# 106	byte				# char. code of file name
# 107	byte				# still more Finder flags
# 116	belong				# total file length
# 120	beshort				# length of add'l header
# 122	byte		129		# for MacBinary II
# 122	byte		130		# for MacBinary III
# 123	byte		129		# minimum version that can read fmt
# 124	beshort				# checksum
#
# This attempts to use the version numbers as a magic number, requiring
# that the first one be 0x80, 0x81, 0x82, or 0x83, and that the second
# be 0x81.  This works for the files I have, but maybe not for everyone's.

122	beshort&0xFCFF	0x8081		Macintosh MacBinary data

# MacBinary I doesn't have the version number field at all, but MacBinary II
# has been in use since 1987 so I hope there aren't many really old files
# floating around that this will miss.  The original spec calls for using
# the nulls in 0, 74, and 82 as the magic number.
#
# Another possibility, that would also work for MacBinary I, is to use
# the assumption that 65-72 will all be ASCII (0x20-0x7F), that 73 will
# have bits 1 (changed), 2 (busy), 3 (bozo), and 6 (invisible) unset,
# and that 74 will be 0.  So something like
# 
# 71 	belong&0x80804EFF 0x00000000 	Macintosh MacBinary data
# 
# >73	byte&0x01	0x01		\b, inited
# >73	byte&0x02	0x02		\b, changed
# >73	byte&0x04	0x04		\b, busy
# >73	byte&0x08	0x08		\b, bozo
# >73	byte&0x10	0x10		\b, system
# >73	byte&0x10	0x20		\b, bundle
# >73	byte&0x10	0x40		\b, invisible
# >73	byte&0x10	0x80		\b, locked
