+ * TFlushOutput class.
+ *
+ * TFlushOutput enables forced flushing of the current output buffer
+ * at (a) certain point(s) in the page, after rendering of all previous
+ * controls has been completed.
+ *
+ * To use TFlushOutput, simply place it in a template where you want
+ * the have the output buffered between the start of the page or the
+ * last TFlushOutput to be sent to the client immediately
+ * <code>
+ * <com:TFlushOutput />
+ * </code>
+ *
+ * You can specify whether you want to keep buffering of the output
+ * (if it was enabled) till the next occourence of a <com: TFlushOutput />
+ * or the end of the page rendering, or stop buffering, by using the
+ * {@link setContinueBuffering ContinueBuffering}.
+ *
