Initial support for generating Visual Studio solution and project files using GYP

build/README.txt

 This directory contains the V8 GYP files used to generate actual project files
 for different build systems.
 
 This is currently work in progress but this is expected to replace the SCons
 based build system.
 
 To use this a checkout of GYP is needed inside this directory. From the root of
-the V8 project do the following
+the V8 project do the following:
 
 $ svn co http://gyp.googlecode.com/svn/trunk build/gyp
 
 To generate Makefiles and build 32-bit version on Linux:
+--------------------------------------------------------
 
 $ GYP_DEFINES=target_arch=ia32 build/gyp_v8
 $ make
 
 To generate Makefiles and build 64-bit version on Linux:
+--------------------------------------------------------
 
 $ GYP_DEFINES=target_arch=x64 build/gyp_v8
 $ make
 
 To generate Makefiles and build for the arm simulator on Linux:
+---------------------------------------------------------------
 
 $ build/gyp_v8 -I build/arm.gypi
 $ make
+
+To generate Visual Studio solution and project files on Windows:
+----------------------------------------------------------------
+
+On Windows an additional third party component is required. This is cygwin in
+the same version as is used by the Chromium project. This can be checked out
+from the Chromium repository. From the root of the V8 project do the following:
+
+> svn co http://src.chromium.org/svn/trunk/deps/third_party/cygwin@66844 third_party/cygwin
+
+To run GYP Python is required and it is reccomended to use the same version as
+is used by the Chromium project. This can also be checked out from the Chromium
+repository. From the root of the V8 project do the following:
+
+> svn co http://src.chromium.org/svn/trunk/tools/third_party/python_26@70627 third_party/python_26
+
+Now generate Visual Studio solution and project files:
+
+> third_party\python_26\python build/gyp_v8 -D target_arch=ia32
+
+Now open build\All.sln in Visual Studio.
