It would be nice to have SageTeX supported in org export to LaTeX. This wouldn't be very hard to add. See http://comments.gmane.org/gmane.emacs.orgmode/58945 for a first draft. We could add this to
sage-auctex.el, though we should probably rename it to
sagetex.el in that case.
Some things to keep in mind: Check if there is already sage in the export process Put it after the first latex * Maybe ask if they want to save it as customized
