# aout: file(1) magic for a.out executable/object/etc entries that
# handle executables on multiple platforms.
#
#
# Little-endian 32-bit-int a.out, merged from bsdi (for BSD/OS, from
# BSDI), netbsd, and vax (for UNIX/32V and BSD)
#
# XXX - is there anything we can look at to distinguish BSD/OS 386 from
# NetBSD 386 from various VAX binaries? The BSD/OS shared library flag
# works only for binaries using shared libraries. Grabbing the entry
# point from the a.out header, using it to find the first code executed
# in the program, and looking at that might help.

# Big-endian 32-bit-int a.out, merged from sun (for old 68010 SunOS a.out),
# mips (for old 68020(!) SGI a.out), and netbsd (for old big-endian a.out).
#
# XXX - is there anything we can look at to distinguish old SunOS 68010
# from old 68020 IRIX from old NetBSD? Again, I guess we could look at
# the first instruction or instructions in the program.
