+"""Core XML support for Python.
+
+This package contains four sub-packages:
+
+dom -- The W3C Document Object Model.  This supports DOM Level 1 +
+       Namespaces.
+
+parsers -- Python wrappers for XML parsers (currently only supports Expat).
+
+sax -- The Simple API for XML, developed by XML-Dev, led by David
+       Megginson and ported to Python by Lars Marius Garshol.  This
+       supports the SAX 2 API.
+
+etree -- The ElementTree XML library.  This is a subset of the full
+       ElementTree XML release.
