this is good to hear....

>So the export filter may not be able to generate templates?

well don't quote me on this because i really didn't investigate it too 
deeply but i think that we can encode the information without compressing it 
and powerpoint should still be able to read it. also, i don't know exactly 
what kind of information is contained in this container but the microsoft 
documentation(which is incomplete and sometimes wrong) says it is a LZW 
compressed container. i guess that it has something to do with templates 
because i have not come across this container in files that do not have a 
template, only files that i created from a template.
in any case, i will make this my first priority on this project. if anyone 
else wants to look into this also, please contact me so that we can chat 
about it...
