+Summary: Python bindings for the libxml2 library
+Group: Development/Libraries
+Requires: libxml2 = %{version}
+Requires: python
+
+%description python
+The libxml2-python package contains a module that permits applications
+written in the Python programming language to use the interface
+supplied by the libxml2 library to manipulate XML files.
+
+This library allows to manipulate XML files. It includes support
+to read, modify and write XML and HTML files. There is DTDs support
+this includes parsing and validation even with complex DTDs, either
+at parse time or later once the document has been modified.

+ TODO for the libxml2 Python wrappers
+
+ $Id$
+
+Things to do:
+-------------
+
+- handling of node.content
+- SAX interfaces
+- error redirections and preformat
+- class hierarchy:
+ + get the generator to output a classes.txt description
+- extensions based on a python.xml description of the new specific
+ interfaces
+- memory debug interfaces
+- enums -> libxml.py
+- spec file: automatically generate for pythonX.Y if found
+- access to XPath variables
+- parserCtxt exposure:
+ - entry points
+ - wrappers
+ - decent interface for setting/getting behaviour
+- xmlBuffer exposure
+- xpathContext, being able to set/get info and clean it up
+- add regression tests
+ - check memory
+ - build tree
+ - saving
+ - SAX flow
+
+
+Done:
+-----
+- class hierarchy:
+ + make specific node type inherit from xmlNode
+- add regression tests
+ - tests/Makefile.am: export the Python class path
+ - xpath queries
+ - xpath extension
