+# 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.
