I've completed renaming Cbuildv2 to Abe, as well as modifying all the
board files for remote testing to match what the new DNS server is
using. Please stop using the existing cbuild2 repository, as all changes
are now done in the new repository. I'll leave the old repository for a
while, I know there are branches there people depend on. For those, I'm
sorry for the pain (having just gone through that myself), but please
migrate any important branches to the new repository. URLs for that are
