+                How to build c-ares using MSVC or Visual Studio
+               =================================================
+
+
+
+  How to build using MSVC from the command line
+  ---------------------------------------------
+
+  Open a command prompt window and ensure that that the environment is
+  properly set up in order to use the compiler tools.
+
+  Change to c-ares source folder where Makefile.msvc file is located and run:
+
+  > nmake -f Makefile.msvc
+
+  This will build all c-ares libraries as well as three sample programs.
+
+  Once the above command has finished a new folder named MSVCXX will exist
+  below the subdir where makefile.msvc is found. The name of the folder
+  depends on the MSVC compiler version being used to build c-ares.
+
+  Below the MSVCXX folder there will exist four folders named 'cares',
+  'ahost', 'acountry', and 'adig'. The 'cares' folder is the one which
+  holds the c-ares libraries you have just generated, the other three
+  hold sample programs that use the libraries.
+
+  The above command builds four versions of the c-ares library, the dynamic
+  and static versions and each of them in release and debug flavours. Each
+  of these are found in folders named dll-release, dll-debug, lib-release,
+  and lib-debug which hang from the 'cares' folder mentioned above. Each
+  sample program also has folders with the same names to reflect which
+  library version it is using.
+
+
+  How to build using Visual Studio 6 IDE
+  --------------------------------------
+
+  A VC++ 6.0 reference workspace (vc6aws.dsw) is available within the 'vc'
+  folder to allow proper building of the library and sample programs.
+
+  1) Open the vc6aws.dsw workspace with MSVC6's IDE.
+  2) Select 'Build' from top menu.
+  3) Select 'Batch Build' from dropdown menu.
+  4) Make sure that the sixteen project configurations are 'checked'.
+  5) Click on the 'Build' button.
+  6) Once the sixteen project configurations are built you are done.
+
+  Dynamic and static c-ares libraries are built in debug and release flavours,
+  and can be located each one in its own subdirectory, dll-debug, dll-release,
+  lib-debug and lib-release, all of them below the 'vc/cares' subdirectory.
+
+  In the same way four executable versions of each sample program are built,
+  each using its respective library. The resulting sample executables are
+  located in its own subdirectory, dll-debug, dll-release, lib-debug and
+  lib-release, below the 'vc/acountry', 'vc/adig' and 'vc/ahost'subdirs.
+
+  These reference VC++ 6.0 configurations are generated using the dynamic CRT.
+
+
+  How to build using Visual Studio 2003 or newer IDE
+  --------------------------------------------------
+
+  First you have to convert the VC++ 6.0 reference workspace and project files
+  to the Visual Studio IDE version you are using, following next steps:
+
+  1) Open vc\vc6aws.dsw with VS20XX.
+  2) Allow VS20XX to update all projects and workspaces.
+  3) Save ALL and close VS20XX.
+  4) Open vc\vc6aws.sln with VS20XX.
+  5) Select batch build, check 'all' projects and click 'build' button.
+
+  Same comments relative to generated files and folders as done above for
+  Visual Studio 6 IDE apply here.
+
+
+  Relationship between c-ares library file names and versions
+  -----------------------------------------------------------
+
+  c-ares static release library version files:
+
+      libcares.lib -> static release library
+
+  c-ares static debug library version files:
+
+      libcaresd.lib -> static debug library
+
+  c-ares dynamic release library version files:
+
+      cares.dll -> dynamic release library
+      cares.lib -> import library for the dynamic release library
+      cares.exp -> export file for the dynamic release library
+
+  c-ares dynamic debug library version files:
+
+      caresd.dll -> dynamic debug library
+      caresd.lib -> import library for the dynamic debug library
+      caresd.exp -> export file for the dynamic debug library
+      caresd.pdb -> debug symbol file for the dynamic debug library
+
+
+  How to use the c-ares static libraries
+  --------------------------------------
+
+  When using the c-ares static library in your program, you will have to
+  define preprocessor symbol CARES_STATICLIB while building your program,
+  otherwise you will get errors at linkage stage.
