After the panic I felt when I found out that riocar.org was offline, I decided to make a repo (empeg-all) for all the known documentation, source code and binaries.

The riocar.org site is back up (yay), but is backed up there; we can't loose the FAQs, and drive and geek guides! I'm still working on enriching the collection, but the basics are all in it:
