Powerpoint presentations?!?

I've been asked to write code that will dynamically generate Microsoft Powerpoint presentations. It has to assemble collections of pages, and possibly substitute a word or phrase here and there (mailmerge style). There doesn't seem to be a published document describing Powerpoint file format or capabilities. The only generation tool I can find is a sourceforge.net project that has no files. The only conversion tools I can find convert FROM powerpoint, not TO it. Heck, I run FreeBSD at home so I can't actually VIEW ppt files. Any advice? Do I tell the customer that it's Flash or PDF or find another developer? I'd *much* rather do this in pdflib or ming, but that may just not be possible.... -- Paul Chvostek <paul@it.ca> Operations / Abuse / Whatever it.canada, hosting and development http://www.it.ca/
