"""
This file extracts and builds library dependencies libpng, zlib, & freetype2 on
MS Windows.  It also extract tcl/tk for the header files.

There are four possible build targets -- one for each permutation of VS 2008,
2010 and 32/64 bit.  This builds the configuration that matches the Python
install that is executing.

For Python 2.6, 2.7, 3.2:

- VS 2008, 32 bit -- Windows SDK v7.0
- VS 2008, 64 bit -- Windows SDK v7.0

For Python 3.3, 3.4:

- VS 2010, 32 bit -- Windows SDK v7.1
- VS 2010, 64 bit -- Windows SDK v7.1
