each existing authorized derivative work, of my zoo archive
14+
program as of the date at the bottom of this copyright statement.

17+
unmodified form for any purpose, whether commercial or

3. CREATION OF DERIVATIVE WORKS: You may create and distribute
22+
derivative works made from any source code files that are part of
23+
this software, provided that you (a) preserve all copyright
24+
notices and author attributions, (b) do not create, whether
25+
deliberately or through negligence, any derivative work that
26+
violates the compatibility goals describe in the reference manual
27+
for zoo 2.1, (c) do not attempt to restrict the distribution or
28+
use of the derivative work by others, (d) make the fully commented
29+
source code of the derivative work available to me at no cost if
30+
I so request, and make no attempt to restrict the distribution
31+

INSTALLATION
3+
4+
This is version 2.1 of the zoo archiver. It includes improved compression,
5+
better online help, VAX/VMS file timestamp preservation, faster
6+
uncompression, and other features that are described in the accompanying
7+
manual ("zoo.1" or "zoo.man").
8+
9+
The supplied makefile contains a number of targets for selected systems.
10+
Type "make help" for help from the makefile. Also, for VAX/VMS
11+
systems, see the file vmsbugs.doc for VMS-specific information.
12+
13+
The file ``options.h'' defines preprocessor symbols for the various sys-
14+
tems. In most cases, given a reasonably powerful C compiler and
15+
library, you will be able to find a combination of options that will
16+
work. Documentation for these options is in the file ``options.doc''.
17+
18+
Other machine-dependent code and definitions are in machine.h,
19+
machine.c, and portable.h. Also, the amount of memory used for some
20+
arrays can be customized by defining symbols that are described and used
21+
in zoomem.h.
22+
23+
The low-level input/output routines are in portable.c. In most cases
24+
these will not need to be modified.
25+
26+
On machines with older (Intel-style) architectures zoo requires the
27+
large memory model. Compiling with the small memory model will
28+
cause problems.
29+
30+
EXTRACT-ONLY VERSION. For a new system, your first concern should be
31+
the ability to extract and list zoo archives. For this purpose try com-
32+
piling booz (which stands for Barebones Ooz) (currently version 2.0),
33+
which is small and portable. It is distributed separately from zoo.
34+
35+
KNOWN BUGS
36+
37+
1. The filter mode of zoo 2.1 appears to compresses and uncompresses
38+
correctly, but often reports an "Uncompression error" even when
39+
uncompression was successful.
40+
41+
2. It is possible for zoo 2.1 to fail to detect an out of disk space
42+
situation when adding files to a zoo archive.
43+
44+
3. The MS-DOS version of zoo 2.1 may unnecessarily report an error
45+
when extracting a file to standard output. Normal file extraction
46+
to disk is not affected.
47+
48+
These bugs are expected to be fixed in the next release.
