How do you annotate a branch?

Question

Is there any way to annotate a branch? It would be nice to be able to do something like:

$ git notes add branch-name -m \'This branch is for whatever\'

Using Brian's solution I've created git-note. You can use it like:

$ git note "Some note" # set note for current branch
$ git note -b branch # see note for branch
$ git note -l # list all the branches with theirs' notes
