Subject: [PATCH] Bigger warnings that new users should use SXSSF, and not mess
 around with the XML themselves

 /**
  * Demonstrates a workaround you can use to generate large workbooks and avoid OutOfMemory exception.
  *
- * The trick is as follows:
+ * Note - You probably <em>don't want to use this approach any more</em>! POI
+ *  now includes the SXSSF which handles all of this for you, you should
+ *  be using that instead! This code remains mostly for historical interest.
+ * <p>
+ * See <a "http://poi.apache.org/spreadsheet/how-to.html#sxssf">
+ *     http://poi.apache.org/spreadsheet/how-to.html#sxssf</a>.
+ * <p>
+ * If you really want to use this approach, which is also the one that SXSSF
+ * does for you, it works as follows:
+ * 
  * 1. create a template workbook, create sheets and global objects such as cell styles, number formats, etc.
  * 2. create an application that streams data in a text file
  * 3. Substitute the sheet in the template with the generated data
  *
  * <p>
- *      Since 3.8-beta3 POI provides a low-memory footprint SXSSF API which implementing the "BigGridDemo" strategy.
- *      XSSF is an API-compatible streaming extension of XSSF to be used when
- *      very large spreadsheets have to be produced, and heap space is limited.
- *      SXSSF achieves its low memory footprint by limiting access to the rows that
- *      are within a sliding window, while XSSF gives access to all rows in the
- *      document. Older rows that are no longer in the window become inaccessible,
- *      as they are written to the disk.
