FWKCS(TM) Contents_Signature System, Ver. 1.22, 1993 Aug 10.
(C)Copyright Frederick W. Kantor 1989-1993. All rights reserved.

Summary: The FWKCS(TM) Contents_Signature System provides a powerful platform
         supporting contents_signature functions.  Among other applications,
         FWKCS is used on giant bulletin boards for protecting against
         duplicate files and against accidentally uploaded commercial files.

         The FWKCS system has been shown, experimentally, to provide
         statistical resolution typically more than one thousand times as good
         as the best that is mathematically possible for the 32_bit CRC to do.

         In the current release, all functions are enabled, including the
         client/host configuration, to permit testing. (See "Notes", below.)

         And registration for personal use, or for a bulletin board of up
         to ten nodes, is only $20.00 (!) (plus any applicable taxes).

         The low prices, the automated installation procedures ranging from
         simple to complex, and the extensive on_line support provided by
         FWKCS on your computer, bring the FWKCS system within reach of
         almost anyone with a computer that can run DOS or a DOS session.

         The kernel for the FWKCS system is an 85,376_byte self_modifying
         re_entrant program written entirely in assembly language. It uses
         a 3,072_byte internal command line, supports 26 73_byte
         dynamically changeable "macros", can read multiple configuration
         files, and can operate on multiple processors so as to dynamically
         allocate work among hosts serving clients on a network.

         Many powerful internal functions are brought out for other uses,
         including the 520_key sorting function limited by the maximum file
         size which the operating system can handle (e.g., for DOS,
         slightly less than 4 Gigabytes).

Important: FWKCS(TM) is provided on a test_before_you_decide basis.

           Your use of this software is at solely your own risk: please have
           proper backups of your files.

New or changed in FWKCS(TM) Version 1.22:

Changes in FWKCS.EXE:
~~~~~~~~~~~~~~~~~~~~~
1. All functions are now enabled in an unregistered copy of FWKCS.EXE,
   including all the functions which were previously reserved for only the
   registered version.

2. An unregistered copy of FWKCS.EXE now looks for REGISTER.FRM in the same
   directory in which FWKCS.EXE is located, even if FWKCS is called via PATH.
   In effect, REGISTER.FRM is used as a temporary key.  A registered copy of
   FWKCS saves time, because it does not have to verify REGISTER.FRM.

3. Added 3 exit errorlevels:

    94 - internal date tampered.
    95 - incongruous system date, and FWKCS unregistered.
    96 - REGISTER.FRM missing or defective, and FWKCS unregistered.

4. Added code to process a defective type of "zipfile, and option z5 to
   suppress such special treatment. Someone apparently released a supposed
   "zipfile" packager which fails to comply with Phil Katz's specification
   as to how disks are labeled in the zipfile central directory: the
   spurious labelling designates the disk containing the central directory
   as starting on disk 01, which would be the second disk of a
   disk_spanning zipfile, and labels the disk containing the start of a
   file as 00, which would be the first disk. The new default is to
   recognize that that 01 disk label is spurious, when such a "zipfile" is
   not part of a self_extracting package.  Option z5 suppresses that
   special treatment; e.g., z5 can help block such misuse of the zipfile
   format.  Option z5 is for use under Auxiliary Functions 3-6.


Changes in FWKCSC.COM, FWKDG.COM, FWKHI.COM, FWKCSS.COM, and FWKCST.COM:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1. Matched version numbers to FWKCS version number.


New or Changed in .BAT and .BAS programs:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1. Changed: testing, use, and support of registered status (many programs),
   re new treatment of registration, with all functions enabled in
   unregistered copies of FWKCS; these changes saved space in the complete
   package.

2. Revised the installation procedures to support automatic installation of
   an X_ADD.LST exclusion list.


Changed in REGISTER.FRM:
~~~~~~~~~~~~~~~~~~~~~~~~
1. Revised in a way more favorable for the user, including reduced prices.

2. Listed both FWKCS and LOOKUP packages. This file, REGISTER.FRM, is used
   as an enabling "key" for unregistered copies of the FWKCS kernel, which
   is used in both the FWKCS and the LOOKUP packages.


Notes:
~~~~~~
1. All the functions which were previously reserved for the registered
   version, are now enabled in the unregistered copy. To run an
   unregistered copy of FWKCS, keep a copy of REGISTER.FRM in the same
   directory with FWKCS.EXE.

2. FWKCS(TM) is provided on a test_before_you_decide basis. Suggested test
   time is two weeks.

   If this software is used in a public, commercial, school, institutional,
   or governmental environment, then the test period is restricted to no
   more than 30 days.

   The program is not free -- if you do not register, you should
   discontinue using it.

3. The remote lookup functions are available in a relatively small kit,
   FWKLU122.ZIP, released 1993 Aug 10.  If you run a BBS, you may wish to
   get the FWKLU122.ZIP kit for your users, especially if your BBS is a
   "feeder BBS" and many of your users are other BBS's.  The kit comes with
   instructions, and contains a short bulletin, FWKLU122.BLT, suitable for
   posting.
