1.1 ! misho 1: ZLIB DATA COMPRESSION LIBRARY
! 2:
! 3: zlib 1.2.3 is a general purpose data compression library. All the code is
! 4: thread safe. The data format used by the zlib library is described by RFCs
! 5: (Request for Comments) 1950 to 1952 in the files
! 6: http://www.ietf.org/rfc/rfc1950.txt (zlib format), rfc1951.txt (deflate format)
! 7: and rfc1952.txt (gzip format). These documents are also available in other
! 8: formats from ftp://ftp.uu.net/graphics/png/documents/zlib/zdoc-index.html
! 9:
! 10: All functions of the compression library are documented in the file zlib.h
! 11: (volunteer to write man pages welcome, contact zlib@gzip.org). A usage example
! 12: of the library is given in the file example.c which also tests that the library
! 13: is working correctly. Another example is given in the file minigzip.c. The
! 14: compression library itself is composed of all source files except example.c and
! 15: minigzip.c.
! 16:
! 17: To compile all files and run the test program, follow the instructions given at
! 18: the top of Makefile. In short "make test; make install" should work for most
! 19: machines. For Unix: "./configure; make test; make install". For MSDOS, use one
! 20: of the special makefiles such as Makefile.msc. For VMS, use make_vms.com.
! 21:
! 22: Questions about zlib should be sent to <zlib@gzip.org>, or to Gilles Vollant
! 23: <info@winimage.com> for the Windows DLL version. The zlib home page is
! 24: http://www.zlib.org or http://www.gzip.org/zlib/ Before reporting a problem,
! 25: please check this site to verify that you have the latest version of zlib;
! 26: otherwise get the latest version and check whether the problem still exists or
! 27: not.
! 28:
! 29: PLEASE read the zlib FAQ http://www.gzip.org/zlib/zlib_faq.html before asking
! 30: for help.
! 31:
! 32: Mark Nelson <markn@ieee.org> wrote an article about zlib for the Jan. 1997
! 33: issue of Dr. Dobb's Journal; a copy of the article is available in
! 34: http://dogma.net/markn/articles/zlibtool/zlibtool.htm
! 35:
! 36: The changes made in version 1.2.3 are documented in the file ChangeLog.
! 37:
! 38: Unsupported third party contributions are provided in directory "contrib".
! 39:
! 40: A Java implementation of zlib is available in the Java Development Kit
! 41: http://java.sun.com/j2se/1.4.2/docs/api/java/util/zip/package-summary.html
! 42: See the zlib home page http://www.zlib.org for details.
! 43:
! 44: A Perl interface to zlib written by Paul Marquess <pmqs@cpan.org> is in the
! 45: CPAN (Comprehensive Perl Archive Network) sites
! 46: http://www.cpan.org/modules/by-module/Compress/
! 47:
! 48: A Python interface to zlib written by A.M. Kuchling <amk@amk.ca> is
! 49: available in Python 1.5 and later versions, see
! 50: http://www.python.org/doc/lib/module-zlib.html
! 51:
! 52: A zlib binding for TCL written by Andreas Kupries <a.kupries@westend.com> is
! 53: availlable at http://www.oche.de/~akupries/soft/trf/trf_zip.html
! 54:
! 55: An experimental package to read and write files in .zip format, written on top
! 56: of zlib by Gilles Vollant <info@winimage.com>, is available in the
! 57: contrib/minizip directory of zlib.

! 60: Notes for some targets:
! 61:
! 62: - For Windows DLL versions, please see win32/DLL_FAQ.txt
! 63:
! 64: - For 64-bit Irix, deflate.c must be compiled without any optimization. With
! 65: -O, one libpng test fails. The test works in 32 bit mode (with the -n32
! 66: compiler flag). The compiler bug has been reported to SGI.
! 67:
! 68: - zlib doesn't work with gcc 2.6.3 on a DEC 3000/300LX under OSF/1 2.1 it works
! 69: when compiled with cc.
! 70:
! 71: - On Digital Unix 4.0D (formely OSF/1) on AlphaServer, the cc option -std1 is
! 72: necessary to get gzprintf working correctly. This is done by configure.
! 73:
! 74: - zlib doesn't work on HP-UX 9.05 with some versions of /bin/cc. It works with
! 75: other compilers. Use "make test" to check your compiler.
! 76:
! 77: - gzdopen is not supported on RISCOS, BEOS and by some Mac compilers.
! 78:
! 79: - For PalmOs, see http://palmzlib.sourceforge.net/
! 80:
! 81: - When building a shared, i.e. dynamic library on Mac OS X, the library must be
! 82: installed before testing (do "make install" before "make test"), since the
! 83: library location is specified in the library.
! 84:
! 85:
! 86: Acknowledgments:
! 87:
! 88: The deflate format used by zlib was defined by Phil Katz. The deflate
! 89: and zlib specifications were written by L. Peter Deutsch. Thanks to all the
! 90: people who reported problems and suggested various improvements in zlib;
! 91: they are too numerous to cite here.
