Git Pivotal

git pivotal --start <branch_01234567>|<01234567>
  Creates a new branch, sets its upstream to the correct remote branch then
  sets the task state to 'started'. If the branch name is omitted, the script
  will use the name of the current branch. If the branch name only contain an
  issue ID, the script will try to make use of the _git_pivotal completion.

git pivotal --clean
