+Building instructions for the DLL versions of Zlib 1.2.3
+========================================================
+
+This directory contains projects that build zlib and minizip using
+Microsoft Visual C++ 7.0/7.1, and Visual C++ .
+
+You don't need to build these projects yourself. You can download the
+binaries from:
+  http://www.winimage.com/zLibDll
+
+More information can be found at this site.
+
+
+Build instructions for Visual Studio 7.x (32 bits)
+--------------------------------------------------
+- Uncompress current zlib, including all contrib/* files
+- Download the crtdll library from
+    http://www.winimage.com/zLibDll/crtdll.zip
+  Unzip crtdll.zip to extract crtdll.lib on contrib\vstudio\vc7.
+- Open contrib\vstudio\vc7\zlibvc.sln with Microsoft Visual C++ 7.x
+  (Visual Studio .Net 2002 or 2003).
+
+Build instructions for Visual Studio 2005 (32 bits or 64 bits)
+--------------------------------------------------------------
+- Uncompress current zlib, including all contrib/* files
+- For 32 bits only: download the crtdll library from
+    http://www.winimage.com/zLibDll/crtdll.zip
+  Unzip crtdll.zip to extract crtdll.lib on contrib\vstudio\vc8.
+- Open contrib\vstudio\vc8\zlibvc.sln with Microsoft Visual C++ 8.0
+
+Build instructions for Visual Studio 2005 64 bits, PSDK compiler
+----------------------------------------------------------------
+at the time of writing this text file, Visual Studio 2005 (and 
+  Microsoft Visual C++ 8.0) is on the beta 2 stage.
+Using you can get the free 64 bits compiler from Platform SDK, 
+  which is NOT a beta, and compile using the Visual studio 2005 IDE
+see http://www.winimage.com/misc/sdk64onvs2005/ for instruction
+
+- Uncompress current zlib, including all contrib/* files
+- start Visual Studio 2005 from a platform SDK command prompt, using
+  the /useenv switch
+- Open contrib\vstudio\vc8\zlibvc.sln with Microsoft Visual C++ 8.0
+
+
+Important
+---------
+- To use zlibwapi.dll in your application, you must define the
+  macro ZLIB_WINAPI when compiling your application's source files.
+
+
+Additional notes
+----------------
+- This DLL, named zlibwapi.dll, is compatible to the old zlib.dll built
+  by Gilles Vollant from the zlib 1.1.x sources, and distributed at
+    http://www.winimage.com/zLibDll
+  It uses the WINAPI calling convention for the exported functions, and
+  includes the minizip functionality. If your application needs that
+  particular build of zlib.dll, you can rename zlibwapi.dll to zlib.dll.
+
+- The new DLL was renamed because there exist several incompatible
+  versions of zlib.dll on the Internet.
+
+- There is also an official DLL build of zlib, named zlib1.dll. This one
+  is exporting the functions using the CDECL convention. See the file
+  win32\DLL_FAQ.txt found in this zlib distribution.
+
+- There used to be a ZLIB_DLL macro in zlib 1.1.x, but now this symbol
+  has a slightly different effect. To avoid compatibility problems, do
+  not define it here.
