* Fixed exceptions produced by LibYAML bindings.
* 'yaml.load()' raises an exception if the input stream contains
more than one YAML document.
+* Improved compatibility with Python 2.3.
* Use setuptools for setup.py. If you want to build optional LibYAML
bindings, run 'python setup.py --with-libyaml install'. Building
LibYAML bindings no longer requires PyRex installed.
