Author:       Jean-loup Gailly and Mark Adler
Uploader:     carsten larsen mail com (Carsten Larsen)

Version:      1.2.8
Architecture: m68k-amigaos >= 3.0.0

DESCRIPTION

  This is a port of Jean-loup Gailly and Mark Adlers famous data compression
  library for development on AmigaOS 3.x

ABOUT

  zlib is designed to be a free, general-purpose, legally unencumbered -- that
  is, not covered by any patents -- lossless data-compression library for use
  on virtually any computer hardware and operating system. The zlib data format
  is itself portable across platforms.

  Unlike the LZW compression method used in Unix compress(1) and in the GIF
  image format, the compression method currently used in zlib essentially never
  expands the data. (LZW can double or triple the file size in extreme cases.)
  zlib's memory footprint is also independent of the input data and can be re-
  duced, if necessary, at some cost in compression. A more precise, technical
  discussion of both points is available on another page.

  zlib was written by Jean-loup Gailly (compression) and Mark Adler (decompres-
  sion). Jean-loup is also the primary author/maintainer of gzip(1), the author
  of the comp.compression FAQ list and the former maintainer of Info-ZIP's Zip;
  Mark is also the author of gzip's and UnZip's main decompression routines and
  was the original author of Zip. Not surprisingly, the compression algorithm
  used in zlib is essentially the same as that in gzip and Zip, namely, the
  'deflate' method that originated in PKWARE's PKZIP 2.x.
  
USAGE

  Included binaries were cross-compiled with an AmigaOS compatible GCC using
  the following configuration:
  CHOST=m68k-amigaos CFLAGS="-O3 -noixemul" ./configure

  Two binaries are supplied for testing: minigzip and example. Be sure to read
  the source code for minigzip before using it.	

  zlib is needed when building other applications. To use zlib with GCC either
  copy zlib.a to your library directory and use the switch -lz or compile the
  source yourself using the desired configuration. A partial list of over 500
  applications using zlib is available from the zlib homepage:
  http://zlib.net/apps.html

  The data format used by the zlib library is described by RFCs (Request for
  Comments) 1950 to 1952 in the files http://tools.ietf.org/html/rfc1950 (zlib
  format), rfc1951 (deflate format) and rfc1952 (gzip format).

SECURITY

  Versions 1.1.4 (March 2002) and later eliminate an earlier potential security
  vulnerability. Any software that is linked against or derived from an earlier
  version of zlib should be upgraded immediately.
