file command extension

[drl at vuse.vanderbilt.edu]

I want to do something that is probably simple but I don't see how to
do it.  Specifically, I want to teach the file command on a Sun4
running SunOS 4.1 to correctly recognize and describe an HP9K300
HP-UX7.0 binary executable.  Sun3s and Sun4s already recognize
executables for the other architecture but now I want to handle formats
from another vndor.  More generally, I'd like to setup file to
recognize non-local executable formats. Can this be done simply with
the /etc/magic file?  If so, please *mail* me what I need to do.

	Thanks,
