I'm giving a talk tomorrow on org-mode and R, and I'm having an exporting
problem that's tripping me up.

Usually when I export code/output sections to HTML, they get CSS classes
like "src-R" for R code, "src-perl" for perl code, "example" for output.
 But now they're all "example".  Has anyone seen this?

Having different classes lets me do stuff like this:
http://article.gmane.org/gmane.emacs.orgmode/46301

Maybe it's the new exporter?  I'm using org-mode 7.9.3d.

I can try downgrading, is there a location for older versions of orgmode?
