+# intel: file(1) magic for x86 Unix
+#
+# Various flavors of x86 UNIX executable/object (other than Xenix, which
+# is in "microsoft"). DOS is in "msdos"; the ambitious soul can do
+# Windows as well.
+#
+# Windows NT belongs elsewhere, as you need x86 and MIPS and Alpha and
+# whatever comes next (HP-PA Hummingbird?). OS/2 may also go elsewhere
+# as well, if, as, and when IBM makes it portable.
+#
+# The `versions' should be un-commented if they work for you.
+# (Was the problem just one of endianness?)
