This section is intended for diagrams (UML/etc) that help explain HSSF.
Have more? Add a new "bug" to the bug database with [DOCUMENTATION] prefacing the description and a link to the file on an http server somewhere. If you don't have your own webserver, then you can email it to (acoliver at apache dot org) provided its < 5MB. Diagrams should be in some format that can be read at least on Linux and Windows. Diagrams that can be edited are preferrable, but lets face it, there aren't too many good affordable UML tools yet! And no they don't HAVE to be UML... just useful.
