git observe [branches]
The observe command makes some of your branches observed branches.
Examples
Observe the current branch:
git observe
Observe branches "alpha" and "beta":
git observe alpha beta
Check out a remote branch (that exists at origin but not on your local machine) and make it observed:
git observe somebody-elses-branch
Convert the current observed branch back to a feature branch:
git hack
Convert the observed branches "alpha" and "beta" back to feature branches:
git hack alpha beta
