-# Zlib
-
-Zlib is a compression tool from [http://zlib.net](http://zlib.net).
-
-The current version is 1.2.7.3 released Apr 13, 2013 and is VERY stable.
-
-PHP on Windows uses the static version of the library, but can be custom
-compiled to link to the dll version, simply remove the static version of the
-library from your LIB path when compiling.
-
-### Building for PHP
-
-
-    nmake -f win32/Makefile.msc
-
-This will create 32 or 64 bit zlib_a.lib depending on target used. For the other build options see instructions at the top of win32/Makefile.msc.

- Compile assembly code (with Visual Studio Command Prompt) by running:
-   bld_ml64.bat (in contrib\masmx64)
-   bld_ml32.bat (in contrib\masmx86)
- Open contrib\vstudio\vc9\zlibvc.sln with Microsoft Visual C++ 2008

-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.
