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