What is the HSSF "eventmodel"?
When will all the documentation be ported to the new site?

The HSSF eventmodel package is a new API for reading XLS files more efficiently. It does require more knowledge on the part of the user, but reduces memory consumption by more than tenfold. It is based on the AWT event model in combination with SAX. If you need read-only access to a given XLS file, this is the best way to do it.

Soon, very soon.
