                            COPYRIGHT


The following rules apply only to the zoo archiver itself.
Currently, all extract-only programs, and all supporting utili-
ties, are fully in the public domain and are expected to remain so
for the forseeable future.


               Copyright Statement for Version 1.71

The distribution restrictions placed on zoo versions 1.71 and ear-
lier are now relaxed.  Version 1.71 and earlier source and the
AmigaDOS and MS-DOS binary files may be distributed for any pur-
pose, whether commercial or noncommercial, by anybody, provided
(a) the files are distributed unmodified and (b) the recipient is
notified in advance of being provided the software that "version
1.71 is an outdated version and version 2.00 and higher versions
are now available from other sources".  However, creation and dis-
tribution of any derivative work is governed by the copyright
statement for versions 2.00 and 2.01.


          Copyright Statement for Versions 2.00 and 2.01

The following conditions apply to the C source code, the MS-DOS
support package, and to the MS-DOS executable code.  Distribution
conditions for J. Brian Waters's AmigaDOS implementation may
differ and will be stated in the copyright statement accompanying
it.

"This program" refers to versions 2.00 and 2.01 and separately to
each subsequent version of the Zoo archiver and to all derivative
works thereof.  "Distribution right" means any copyright, compila-
tion copyright, license, or other right to control distribution or
copying.  "Compiled code" means software that can be executed by a
computer system.

This program is copyrighted but its distribution for noncommercial
purposes is permitted, with the following restrictions.

   - You are prohibited from distributing this program as part of
     any package over which you claim a distribution right.  This
     restriction does not apply if any distribution right is
     claimed only over individual items that you own or for which
     the distribution right has been explicitly assigned to you,
     and not over the package as a collection.

   - You are prohibited from making this program available for
     downloading via telecommunications if you charge a total of
     more than $8.00 per hour at 1200 bps during evening and night
     hours.

   - You are prohibited from distributing this program as compiled
     code unless you also distribute the source code from which
     the compiled code was obtained.  This restriction does not
     apply if the compiled code was created by me.

   - You are prohibited from creating, from this program, any
     derivative work over which you claim a distribution right.

   - You are prohibited from creating from this program, whether
     deliberately or through negligence, any derivative work that
     violates the compatibility goals stated in the user manual
     for this program.

   - You may use this program, and any derivative works that you
     create, internally within your own organization free of
     charge.  You may distribute such derivative works outside
     your organization provided you adhere to all other conditions
     of this copyright policy.

The above restrictions may be relaxed by special agreement; please
contact me for details.

Many users were very confused by my zoo copyright policy.  Several
people whose opinions I respect thought the cause of easy data
compression and interchange would be better served if I changed the
policy.  I also kept getting queries from commercial users who were
afraid of legal problems unless they got my written permission to use
the archiver.
Therefore:
            COPYRIGHT STATEMENT FOR ZOO ARCHIVE PROGRAM
1.   "This software" refers separately to each existing version, and
     each existing authorized derivative work, of my zoo archive
     program as of March 31, 1989.
2.   This copyright statement supersedes all previous copyright
     statements made for this software.
3.   DISTRIBUTION IN UNMODIFIED FORM:  You may copy this software in
     unmodified form for any purpose, whether commercial or
     noncommercial, provided that you make no attempt to restrict
     distribution of it by others.
4.   CREATION OF DERIVATIVE WORKS:  You may create and distribute
     derivative works made from any source code files that are part of
     this software, provided that you (a) preserve all copyright
     notices and author attributions, (b) do not create, whether
     deliberately or through negligence, any derivative work that
     violates the compatibility goals describe in the reference manual
     for zoo 2.01, (c) do not attempt to restrict the distribution or
     use of the derivative work by others, (d) make the original fully
     commented source code available to me at no cost if I so request,
     and (e) make no attempt to restrict the distribution or use of
     this source code.
5.   NO WARRANTY.  I make no claim that this software is free of defects.
     I do not accept any legal obligation to provide any bug fixes or
     any other type of support whatsoever.  I disclaim all liability
     for damages, whether direct or consequential.
6.   EXCEPTIONS:  Exceptions to the above conditions are probably
     possible.  Please contact me to negotiate.
7.   The prohibition against incompatible derivative works does not 
     necessarily imply that the archiver and the archive format cannot
     be enhanced.  However, if any incompatibility is created, it may
     be done only with my permission.
