This is a phenomenally exciting addition.  Combining this with the
htmlized code examples in html export, and the option for \LaTeX export,
org has clearly just vaulted past the rest of the field for literate
programming.  Expect a tutorial from me in the next few weeks about
using org with RWeave (the R variant of SWeave).  This will be a
fantastic way to write articles that include statistical analyses and
figures.

That said, don't be surprised if by opening this door you end up with
some new feature requests from me :)  One addition that I can already
see being interested in is the evaluation of embedded code before
export, so that the results of the code are included along with the
source.  Obviously, there are security issues here that will need to be
thought about, but I'd like to see if we could make this work.

Greedy feature requests aside, this is very, very cool.

I can tell you now that C-c C-c is almost as overloaded in R-mode (from
the package ESS) as it is in org-mode, and I will want it to have its
R-mode interpretation while I edit R code.  While I'm writing, I'll try
to keep an eye out for sensible ways of jumping out of coding mode and
back to org-mode.

Thanks for this release!
