We don't need full YAML spec implementation for package metadata format
in distutils (and for other configs too). Therefore..

Full YAML implementation by PyYAML may be good in general, but for this
simple case it is huge, unsafe, slow, C-based, which means the parsing
logic is not translatable (i.e. with PythonJS) and can not be optimized with
future platform-dependent GPU and CPU cache level 2 tweakers of PyPy
JIT.
