    Device drivers, system calls, and other items related to the UNIX
    kernel.

    ACCSLSTS.TAR
        Modifications to the 4.2BSD kernel to support access control lists.
        Contributor: Jeff Glass <jjg@security.uucp>
    DEV_FD.TAR
        A "/dev/fd" (reference a file descriptor as a file) driver for
        4.3BSD.
        Contributor: Arnold D. Robbins <arnold@emory.uucp>
    DHU_11.TAR
        A 4.2BSD driver for a DEC DHU-11.
        Contributor: Adrian Pell <adrian@cs.reading.uucp>
    DIALINOT.TAR
        Modifications to the 4.3BSD kernel tty driver to allow a modem
        port to be used for both dialin and dialout purposes.
        Contributor: Chris Torek <chris@mimsy.umd.edu>
    IPMLTCST.TAR
        The IP Multicast Extensionts from the VMTP project at Stanford Univ.
        Extensions to 4.3BSD and related systems (SunOS, Ultrix) to support
        IP Multicasting as specified in RFC 1054.  Release  1.2.
        Contributor: Steve Deering <deering@pescadero.stanford.edu>
    LOADABLD.TAR
        A system to allow loadable device drivers on the Sun workstation.
        Allows the development and debugging of device drivers without
        the constant relink-the-kernel reboot-the-system hassles.
        Should be portable to any 4.xBSD environment.
        Contributor: Lee Hasiuk <hasiuk@spp2.uucp>
    NLIST1.TAR
        A program which reads kernel variables and displays them.  It can be
        used to monitor variables, display arrays of data structures, or
        linked lists.  Also a full report generator, with a built-in
        calculator.  It's configurable as to how to read variables, etc.
        Comes with configuration files for SunOS, 4.3BSD, System V,
        and Mach.
        Contributor: Chris Bertin <chris@cetia.uucp>
    NLIST2.TAR
        A command-level interface to nlist(3).  Can also dump kernel memory,
        if you have permission.  Should work on any UNIX system with nlist.
        Contributor: Warren Tucker <wht@n4hgf.uucp>
    PTYSNXPC.TAR
        A "pty" driver for the AT&T UNIX-PC.
        Contributor: Eric Herrin <eric@e.ms.uky.edu>
    SCO_PTYS.TAR
        An implementation of Berkeley pseudo ttys for Xenix/386 2.3.  Also
        works on Xenix/286.
        Contributor: Chip Salzenberg <chip@ateng.ateng.com>
    S5NAP.TAR
        An implementation of nap() (fraction of a second sleep) for System V.
        Contributor: Jon Zeeff <zeeff@b-tech.ann-arbor.mi.us>
    SUBNETRP.TAR
        The mods necessary to 4.3BSD to add a subnet ARP hack.  They allow
        a subnet gateway machine to act as a bridge so that only it need
        know of the existence of subnets.  This is quite useful if many
        machines on the local network do not have RFC 950 subnet code.
        Contributor: John Quarterman <jsq@sally.utexas.edu>
    SYSCLTRC.TAR
        A system call trace facility for 4.2BSD UNIX.
        Contributor: Joseph Simonetti <joes@sbcs.uucp>
    ZONK.C
        A kill-by-userid system call.
