- # 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?)
