-The fields are as follows
+.Va short
+fields here are 16-bit integer values, while the
+.Va long
+fields are 32 bit integers. Since PWB UNIX, like the 6th Edition UNIX
+it was based on, only ran on PDP-11 computers, they
+are in PDP-endian format, which has little-endian shorts, and
+big-endian longs. That is, the long integer whose hexadecimal
+representation is 0x12345678 would be stored in four successive bytes
+as 0x34, 0x12, 0x78, 0x56.
+The fields are as follows:

+.It Va h_mode
+The mode specifies both the regular permissions and the file type, and
+it also holds a couple of bits that are irrelevant to the cpio format,
+because the field is actually a raw copy of the mode field in the inode
+representing the file. These are the IALLOC flag, which shows that
+the inode entry is in use, and the ILARG flag, which shows that the
+file it represents is large enough to have indirect blocks pointers in
+the inode.
+The mode is decoded as follows:

+.Ss New Binary Format
+The new binary
+.Nm
+format showed up when cpio was adopted into late 7th Edition UNIX.
+It is exactly like the PWB binary format, described above, except for
+three changes:
+.Pp
+First, UNIX now ran on more than one hardware type, so the endianness
+of 16 bit integers must be determined by observing the magic number at
+the start of the header. The 32 bit integers are still always stored
+with the most significant word first, though, so each of those two, in
+the struct shown above, was stored as an array of two 16 bit integers,
+in the traditional order. Those 16 bit integers, like all the others
+in the struct, were accessed using a macro that byte swapped them if
+necessary.
+.Pp
+Next, 7th Edition had more file types to store, and the IALLOC and ILARG
+flag bits were re-purposed to accommodate these. The revised use of the
+various bits is as follows:
+.Pp
+.Bl -tag -width "MMMMMMM" -compact
+.It 0170000
+This masks the file type bits.
+.It 0140000
+File type value for sockets.
+.It 0120000
+File type value for symbolic links.
+For symbolic links, the link body is stored as file data.
+.It 0100000
+File type value for regular files.
+.It 0060000
+File type value for block special devices.
+.It 0040000
+File type value for directories.
+.It 0020000
+File type value for character special devices.
+.It 0010000
+File type value for named pipes or FIFOs.
+.It 0004000
+SUID bit.
+.It 0002000
+SGID bit.
+.It 0001000
+Sticky bit.
+.It 0000777
+The lower 9 bits specify read/write/execute permissions
+for world, group, and user following standard POSIX conventions.
+.El
+.Pp
+Finally, the file size field now represents a signed 32 bit integer in
+the underlying file system, so the maximum file size has increased to
+2 gigabytes.
+.Pp
+Note that there is no obvious way to tell which of the two binary
+formats an archive uses, other than to see which one makes more
+sense. The typical error scenario is that a PWB format archive
+unpacked as if it were in the new format will create named sockets
+instead of directories, and then fail to unpack files that should
+go in those directories. Running
+.Va bsdcpio -itv
+on an unknown archive will make it obvious which it is: if it's
+PWB format, directories will be listed with an 's' instead of
+a 'd' as the first character of the mode string, and the larger
+files will have a '?' in that position.
