This is a standalone converter for the OpenOffice.org swriter (*.sxw,*.odt)
and  scalc (*.sxc) formats.
It doesn't depend on Open Office or any other external tools or libraries.
There are three output modules:
    * o3read displays a dump of the parse tree
    * o3totxt creates plain text
    * o3tohtml creates html code
Example: unzip -p document.odt content.xml | o3totxt
