Documentation for the release

We're very short on time for revamping the website at the release date.

However, we should have documentation there anyway (I'm thinking about
"toolchain" and "getting started" documentation). I've started merging
the autoproj and orogen documentations so that they end up in the same
look & feel and updating them because of RTT2

Now, where to put those ?

The website seems a logical choice. However,
- the website is filled enough already
- I don't know *how* as the documentation is already static HTML
pages (generated from markdown)

Thoughts ?
