git clean-removed-in-origin

Deletes all local branches corresponding to branches that were already removed in origin.

git push-this-branch [optional flags]

Pushes the current branch only to the default remote.

git tidy-subdirs [-j N]

For each immediate subdirectory of the cwd that is a git repo, checks out its default branch and runs git-clean-removed-in-origin on it. Repos are processed in parallel (-j sets the number of concurrent jobs, default 4) and a summary of successes, skips, and errors is printed at the end.
