I need to maintain some slides in both latex beamer and in powerpoint. (This is to make slides available for instructors elsewhere, too, 90% of which do not know how to use latex and are unwilling to learn it. and I am a latex guy on linux.)
I have tried the route via Libreoffice (and opendocument), but this did not come out well. right now, the best method that I have found is to author pdf in beamer, then run it through a nuance OCR program to get MS Word...and not even go all the way to Powerpoint (which is where I really need to be).
If I only had a markup language that produced nice Powerpoint, I could probably code a perl translator from markdown to this intermediate markup language. (going from markdown to latex beamer is relatively easy.)
I don't think this exists, but hope springs eternal. after all, it is almost 2014 now. does anyone know of a solution?
One solution is to use odpdown: It converts markdown to the OpenOffice Presenter format, which can be imported into PowerPoint.
It is not yet complete, i.e. table support is missing and possibly not running on certain Windows setups, but nevertheless it could be a start. Possibly, you have Linux running, where it seems to work.
