+/**
+ * Helper class around KoStore for writing out OASIS files.
+ * This class helps solving the problem that automatic styles must be before
+ * the body, but it's easier to iterate over the application's objects only
+ * once. So we open a KoXmlWriter into a memory buffer, write the body into it,
+ * collect automatic styles while doing that, write out automatic styles,
+ * and then copy the body XML from the buffer into the real KoXmlWriter.
+ *
+ * The typical use of this class is therefore:
+ *   - write body into bodyWriter() and collect auto styles
+ *   - write auto styles into contentWriter()
+ *   - call closeContentWriter()
+ *   - write other files into the store (styles.xml, settings.xml etc.)
+ *
+ *
+ * TODO: maybe we could encapsulate a bit more things, to e.g. handle
+ * adding manifest entries automatically.
