move v8 src to google dir moving v8 source into main extension move google upstream source dir into v8 ext dir include v8 library in generated bundle prep for 0.4.7 roll the upstream build into the main extension build Documentation was confusing the gem packager. simplify build instructions with bundled v8. Only install scons and build v8 if it has not been built already. Missing CVS.py from the scons library due to ignore patterns. Don't need libv8 anymore, only python 2.5 which is required to build it.

Tool-specific initialization for Microsoft Visual C/C++.

There normally shouldn't be any need to import this module directly.

It will usually be imported through the generic SCons.Tool.Tool()

selection method.
