This directory contains (as of writing) the latest version of V8 on the 3.12 branch. See src/version.cc for the full version number. Use the following to generate the base tree: git clone -b 3.12 git://github.com/v8/v8 These V8 files have been removed from the base tree for cleanliness and to satisfy space constraints: benchmarks/ build/ DEPS Makefile Makefile.android preparser/ samples/ SConstruct src/SConscript src/arm/ src/mips/ test/ And these files have been added to complete the integration with the MongoDB build system: README SConscript [1] [1] The contents of this file are heavily borrowed from V8's src/SConscript.
