//! `slu repos` - at-a-glance working-tree state for every repo under a path.
//!
//! For each repo it shows the current branch, how many files are dirty, and how
//! far ahead/behind its upstream it is - so "which of my repos have uncommitted
//! or unpushed work?" is one command instead of cd-ing through each.
