* the inputting and outputting of OpenDocument Format (ODF) files from

- * improve greatly with time.
+ * improve greatly with time. People should consider this to be a framework
+ * that can be continously upgraded for ever improving fidelity. Potential
+ * developers should especially look in preprocess() and writeTree() to see how
+ * the SVG tree is scanned, read, translated, and then written to ODF.
