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

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