-This directory contains project files for building zlib under various
-Integrated Development Environments (IDE).
-
-If you wish to submit a new project to this directory, you should comply
-to the following requirements.  Otherwise (e.g. if you wish to integrate
-a custom piece of code that changes the zlib interface or its behavior),
-please consider submitting the project to the contrib directory.
-
-
-Requirements
-============
-
-- The project must build zlib using the source files from the official
-  zlib source distribution, exclusively.
-
-- If the project produces redistributable builds (e.g. shared objects
-  or DLL files), these builds must be compatible to those produced by
-  makefiles, if such makefiles exist in the zlib distribution.
-  In particular, if the project produces a DLL build for the Win32
-  platform, this build must comply to the officially-ammended Win32 DLL
-  Application Binary Interface (ABI), described in win32/DLL_FAQ.txt.
-
-- The project may provide additional build targets, which depend on
-  3rd-party (unofficially-supported) software, present in the contrib
-  directory.  For example, it is possible to provide an "ASM build",
-  besides the officially-supported build, and have ASM source files
-  among its dependencies.
-
-- If there are significant differences between the project files created
-  by different versions of an IDE (e.g. Visual C++ 6.0 vs. 7.0), the name
-  of the project directory should contain the version number of the IDE
-  for which the project is intended (e.g. "visualc6" for Visual C++ 6.0,
-  or "visualc7" for Visual C++ 7.0 and 7.1).

+ZLIB DATA COMPRESSION LIBRARY
+
+zlib 1.2.4 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).
+
+All functions of the compression library are documented in the file zlib.h
+(volunteer to write man pages welcome, contact zlib@gzip.org).  Two compiled
+examples are distributed in this package, example and minigzip.  The example_d
+and minigzip_d flavors validate that the zlib1.dll file is working correctly.
+
+Questions about zlib should be sent to <zlib@gzip.org>.  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 DLL_FAQ.txt, and the the zlib FAQ http://zlib.net/zlib_faq.html
+before asking for help.

+Manifest:
+
+The package zlib-1.2.4-win32-x86.zip contains the following files:
+
+  README-WIN32.txt This document
+  ChangeLog        Changes since previous zlib packages
+  DLL_FAQ.txt      Frequently asked questions about zlib1.dll
+  zlib.3.pdf       Documentation of this library in Adobe Acrobat format
+
+  example.exe      A statically-bound example (using zlib.lib, not the dll)
+  example.pdb      Symbolic information for debugging example.exe
+
+  example_d.exe    A zlib1.dll bound example (using zdll.lib)
+  example_d.pdb    Symbolic information for debugging example_d.exe
+
+  minigzip.exe     A statically-bound test program (using zlib.lib, not the dll)
+  minigzip.pdb     Symbolic information for debugging minigzip.exe
+
+  minigzip_d.exe   A zlib1.dll bound test program (using zdll.lib)
+  minigzip_d.pdb   Symbolic information for debugging minigzip_d.exe
+
+  zlib.h           Install these files into the compilers' INCLUDE path to
+  zconf.h          compile programs which use zlib.lib or zdll.lib
+
+  zdll.lib         Install these files into the compilers' LIB path if linking
+  zdll.exp         a compiled program to the zlib1.dll binary
+
+  zlib.lib         Install these files into the compilers' LIB path to link zlib
+  zlib.pdb         into compiled programs, without zlib1.dll runtime dependency
+                   (zlib.pdb provides debugging info to the compile time linker)
+
+  zlib1.dll        Install this binary shared library into the system PATH, or
+                   the program's runtime directory (where the .exe resides)
+  zlib1.pdb        Install in the same directory as zlib1.dll, in order to debug
+                   an application crash using WinDbg or similar tools.
+
+All .pdb files above are entirely optional, but are very useful to a developer
+attempting to diagnose program misbehavior or a crash.  Many additional
+important files for developers can be found in the zlib124.zip source package
+available from http://zlib.net/ - review that package's README file for details.

+people who reported problems and suggested various improvements in zlib; they
