ZOO 2.01 -- MS-DOS BINARY DISTRIBUTION
Repackaged May 1989
This package contains version 2.01 of the Zoo archive program, along with
the supporting utilities Fiz 2.0 and Stuff 2.0
REDISTRIBUTION
Because all the programs in this package support one another, and because it
is nearly impossible to use them properly without the user manuals, I
strongly recommend that everything in this package be distributed together.
If necessary you can distribute the executable programs separately, but you
should in that case be sure to warn the recipient that there is more, and
how and where to get it.
CONTENTS OF THIS PACKAGE
In addition to the file "readme.1st", which you are reading, the following
files are included in this package. File sizes, dates, times, and CRC
values (as found in a zoo archive with the "zoo lC" command) are shown
below.
Length Date Time CRC Name
-------- --------- -------- ---- -------
10716 31 Jan 88 23:40:04 b60f fiz.exe
4132 13 Feb 88 15:09:12 cf97 fiz.man
13004 20 Mar 89 00:32:12 e087 stuff.doc
14928 5 Mar 89 04:58:34 086e stuff.exe
40078 25 Aug 88 18:08:18 27db zoo.exe
53706 24 May 89 21:00:20 88b6 zoo.man
fiz.exe:
-------
Fiz 2.0, the Fix Zoo utility. This program helps recover data from damaged
zoo archives. The existence of fiz.exe does not indicate that zoo archives
are easily damaged (they are not, and they are immune to trailing garbage
added by some file transfer protocols). But should a transmission error
result in a corrupted download of a zoo archive, you will likely be able to
recover the data from most or all of the undamaged parts of the damaged
archive.
fiz.man:
-------
The user manual for Fiz.
stuff.exe:
---------
Stuff 2.0, a file finder for use with Zoo 2.01. This program will generate a
list of pathnames based on selection criteria that you decide. The output
may be fed to Zoo 2.01 through a pipe to allow you to archive one or more
subdirectory hierarchies. Later, the resulting zoo archive can be extracted
to recreate the original subdirectory hierarchy.
stuff.doc:
---------
The user manual for Stuff 2.0.
zoo.exe:
-------
Zoo 2.01, a file archiving program. Currently zoo is available in binary
form for AmigaDOS and MS-DOS and in C source form for MS-DOS, VAX/VMS, and
**IX and look-alike systems. It has been ported to a large number
of systems including various flavors of **IX, Atari/ST, OS-9, and OS/2.
zoo.man:
-------
The user manual for zoo 2.01.
OTHER PROGRAMS
In addition to Zoo, Stuff, and Fiz, which are included in this package, other
supporting programs that you may find useful are:
Sez 2.3: (Self-Extracting Zoo) This program will convert any Zoo archive
to self-extracting form in a few seconds. Self-extraction overhead is less
than 2500 bytes, and the self-extracting archive will recreate the original
contents of the zoo archive when executed on any MS-DOS system. These
self-extracting archives can be extracted on non-MS-DOS systems too with the
help of Fiz 2.0 and Zoo 2.01.
Looz 2.1: (Ooz with List) This program will extract, list, and execute
files from zoo archives on any MS-DOS system. As far as I can tell, Looz is
the only program in existence for MS-DOS systems that allows you to have
executable programs stored in compressed form and execute them by extracting
directly into memory, with no net memory penalty, no need for any temproary
disk space, and with the usual MS-DOS command-line arguments, I/O
redirection, and piping fully available. There are substantial savings in
disk space due to avoiding fragmentation if many small EXE or COM programs
are stored in a zoo archive. For example, if you have 20 tiny programs on a
hard disk, each 100 bytes long, you will typically tie up 40 kilobytes of
disk space (160 kilobytes under some earlier versions of MS-DOS). Stored in
a Zoo archive, these programs will take up about 4 kilobytes or less; if
stored uncompressed, execution can still be virtually instantaneous.
AVAILABILITY OF SOURCE CODE
Source code was posted to the Usenet newsgroup comp.sources.unix in early
1989. I also uploaded it to GEnie's IBM PC RoundTable in late 1988. It may
be available from other sources such as bulletin boards.
