Basically following the information at http://www.xml.com/lpt/a/1638, create a local macro, and run it from the command line:
<source lang="bash">
ooffice2 -invisible "macro:///Standard.MyConverters.SaveAsOOO(/home/greg/projects/slides/executive.ppt)"
</bashsource>
(Note that OOO is just shorthand for OpenOffice.Org)
