20# cpio archives
21#
22# Yes, the top two "cpio archive" formats *are* supposed to just be "short".
23# The idea is to indicate archives produced on machines with the same
24# byte order as the machine running "file" with "cpio archive", and
25# to indicate archives produced on machines with the opposite byte order
26# from the machine running "file" with "byte-swapped cpio archive".
27#
28# The SVR4 "cpio(4)" hints that there are additional formats, but they
29# are defined as "short"s; I think all the new formats are
30# character-header formats and thus are strings, not numbers.

45# Original UNIX archive formats.
46# They were written with binary values in host byte order, and
47# the magic number was a host "int", which might have been 16 bits
48# or 32 bits.  We don't say "PDP-11" or "VAX", as there might have
49# been ports to little-endian 16-bit-int or 32-bit-int platforms
50# (x86?) using some of those formats; if none existed, feel free
51# to use "PDP-11" for little-endian 16-bit and "VAX" for little-endian
52# 32-bit.  There might have been big-endian ports of that sort as
53# well.

145# The first byte is the magic (0x1a), byte 2 is the compression type for
146# the first file (0x01 through 0x09), and bytes 3 to 15 are the MS-DOS
147# filename of the first file (null terminated).  Since some types collide
148# we only test some types on basis of frequency: 0x08 (83%), 0x09 (5%),
149# 0x02 (5%), 0x03 (3%), 0x04 (2%), 0x06 (2%).  0x01 collides with terminfo.
