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