The branch to use is q800-dev

As I rebase the branch regularly, a simple "git pull" will not work.

If the branch already exist locally

  git checkout q800-dev
  git reset --hard vivier/q800-dev

  [I guess the remote name is "vivier"]

otherwise, a simple "git checkout q800-dev" should create the branch
from scrash.
