4# intel:  file(1) magic for x86 Unix
5#
6# Various flavors of x86 UNIX executable/object (other than Xenix, which
7# is in "microsoft").  DOS is in "msdos"; the ambitious soul can do
8# Windows as well.
9#
10# Windows NT belongs elsewhere, as you need x86 and MIPS and Alpha and
11# whatever comes next (HP-PA Hummingbird?).  OS/2 may also go elsewhere
12# as well, if, as, and when IBM makes it portable.
13#
14# The `versions' should be un-commented if they work for you.
15# (Was the problem just one of endianness?)
