+        et_xmlfile is a low memory library for creating large XML files.
+
+        It is based upon the xmlfile module from lxml with the aim of allowing
+        code to be developed that will work with both libraries. It was developed
+        initially for the openpyxl project but is now a standalone module.
+
+        The code was written by Elias Rabel as part of the Python Düsseldorf
+        openpyxl sprint in September 2014.
