+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
+
+$ 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
