+ZLIB DATA COMPRESSION LIBRARY
+
+zlib 1.2.1 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://www.ietf.org/rfc/rfc1950.txt (zlib format), rfc1951.txt (deflate format)
+and rfc1952.txt (gzip format). These documents are also available in other
+formats from ftp://ftp.uu.net/graphics/png/documents/zlib/zdoc-index.html
+
+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 example.c which also tests that the library
+is working correctly. Another example is given in the file minigzip.c. The
+compression library itself is composed of all source files except example.c and
+minigzip.c.
+
+To compile all files and run the test program, follow the instructions given at
+the top of Makefile. In short "make test; make install" should work for most
+machines. For Unix: "./configure; make test; make install" For MSDOS, use one
+of the special makefiles such as Makefile.msc. For VMS, use Make_vms.com or
+descrip.mms.
+
+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://www.zlib.org or http://www.gzip.org/zlib/ 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://www.gzip.org/zlib/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 in
+http://dogma.net/markn/articles/zlibtool/zlibtool.htm
+
+The changes made in version 1.2.1 are documented in the file ChangeLog.
+
+Unsupported third party contributions are provided in directory "contrib".
+
+A Java implementation of zlib is available in the Java Development Kit
+http://java.sun.com/j2se/1.4.2/docs/api/java/util/zip/package-summary.html
+See the zlib home page http://www.zlib.org for details.
+
+A Perl interface to zlib written by Paul Marquess <pmqs@cpan.org> is in the
+CPAN (Comprehensive Perl Archive Network) sites
+http://www.cpan.org/modules/by-module/Compress/
+
+A Python interface to zlib written by A.M. Kuchling <amk@magnet.com> is
+available in Python 1.5 and later versions, see
+http://www.python.org/doc/lib/module-zlib.html
+
+A zlib binding for TCL written by Andreas Kupries <a.kupries@westend.com> is
+availlable at http://www.oche.de/~akupries/soft/trf/trf_zip.html
+
+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, BEOS and by some Mac compilers.
+
+- For PalmOs, see http://palmzlib.sourceforge.net/
+
+- When building a shared, i.e. dynamic library on Mac OS X, the library must be
+  installed before testing (do "make install" before "make test"), since the
+  library location is specified in the library.
+
+
+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.
