     ZLIB DATA COMPRESSION LIBRARY
     
     zlib 1.2.11 is a general purpose data compression library.  All the code is
     thread safe.  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).
     
     All functions of the compression library are documented in the file zlib.h
    (volunteer to write man pages welcome, contact zlib@gzip.org).  A usage example
    of the library is given in the file test/example.c which also tests that
    the library is working correctly.  Another example is given in the file
    test/minigzip.c.  The compression library itself is composed of all source
    files in the root directory.
    
    To compile all files and run the test program, follow the instructions given at
    the top of Makefile.in.  In short "./configure; make test", and if that goes
    well, "make install" should work for most flavors of Unix.  For Windows, use
    one of the special makefiles in win32/ or contrib/vstudio/ .  For VMS, use
    make_vms.com.
    
    Questions about zlib should be sent to <zlib@gzip.org>, or to Gilles Vollant
    <info@winimage.com> for the Windows DLL version.  The zlib home page is
    http://zlib.net/ .  Before reporting a problem, please check this site to
    verify that you have the latest version of zlib; otherwise get the latest
    version and check whether the problem still exists or not.
    
    PLEASE read the zlib FAQ http://zlib.net/zlib_faq.html before asking for help.
    
    Mark Nelson <markn@ieee.org> wrote an article about zlib for the Jan.  1997
    issue of Dr.  Dobb's Journal; a copy of the article is available at
    http://marknelson.us/1997/01/01/zlib-engine/ .
    
    The changes made in version 1.2.11 are documented in the file ChangeLog.
    
    Unsupported third party contributions are provided in directory contrib/ .
    
    zlib is available in Java using the java.util.zip package, documented at
    http://java.sun.com/developer/technicalArticles/Programming/compression/ .
    
    A Perl interface to zlib written by Paul Marquess <pmqs@cpan.org> is available
    at CPAN (Comprehensive Perl Archive Network) sites, including
    http://search.cpan.org/~pmqs/IO-Compress-Zlib/ .
    
    A Python interface to zlib written by A.M. Kuchling <amk@amk.ca> is
    available in Python 1.5 and later versions, see
    http://docs.python.org/library/zlib.html .
    
    zlib is built into tcl: http://wiki.tcl.tk/4610 .
    
    An experimental package to read and write files in .zip format, written on top
    of zlib by Gilles Vollant <info@winimage.com>, is available in the
    contrib/minizip directory of zlib.
    
    
    Notes for some targets:
    
    - For Windows DLL versions, please see win32/DLL_FAQ.txt
    
    - For 64-bit Irix, deflate.c must be compiled without any optimization. With
      -O, one libpng test fails. The test works in 32 bit mode (with the -n32
      compiler flag). The compiler bug has been reported to SGI.
    
    - zlib doesn't work with gcc 2.6.3 on a DEC 3000/300LX under OSF/1 2.1 it works
      when compiled with cc.
    
    - On Digital Unix 4.0D (formely OSF/1) on AlphaServer, the cc option -std1 is
      necessary to get gzprintf working correctly. This is done by configure.
    
    - zlib doesn't work on HP-UX 9.05 with some versions of /bin/cc. It works with
      other compilers. Use "make test" to check your compiler.
    
    - gzdopen is not supported on RISCOS or BEOS.
    
    - For PalmOs, see http://palmzlib.sourceforge.net/
    
    
    Acknowledgments:
    
      The deflate format used by zlib was defined by Phil Katz.  The deflate and
      zlib specifications were written by L.  Peter Deutsch.  Thanks to all the
      people who reported problems and suggested various improvements in zlib; they
      are too numerous to cite here.
