+The options `--contains`, `--merged` and `--no-merged` serves three related
+but different purposes:
+
+- `--contains <commit>` is used to find all branches which will need
+  special attention if <commit> were to be rebased or amended, since those

+- `--merged` is used to find all branches which can be safely deleted,

+
+- `--no-merged` is used to find branches which are candidates for merging
+  into HEAD, since those branches are not fully contained by HEAD.
