sluuz 0.4.2

//! sluuz — a git superset. Binary: `slu`.
//!
//! Every git command passes straight through (`slu commit`, `slu push`, `slu
//! log`), and these extra verbs add cross-repo / history superpowers:
//!   slu search <pattern>   Pickaxe a string through all branches/repos
//!   slu scan   [path]      Audit repositories for leaked secrets
//!   slu repos  [path]      Working-tree state across all repos under a path
//!   slu sync   [path]      Fetch (and optionally fast-forward) all repos
//!   slu tidy   [path]      Find merged, deletable branches across all repos
//!   slu each   <git args>  Run any git command in every repo
//!   slu trace              A prettier history view (does not shadow `git log`)
//!   slu ilog               Interactive log explorer (TUI)
//!   slu ibranch            Interactive branch explorer (TUI)

  slu commit -m \"fix\"       Plain git — passed straight through
  slu push                   …so are push, log, rebase, diff, everything
  slu search -r api_key      Sleuth a string across every repo, all branches
  slu scan -t aws,token      Audit repos for custom secret terms
  slu repos --dirty          Show only repos with uncommitted/unpushed work
  slu sync --pull            Fetch all repos and fast-forward where safe
  slu tidy                   List merged branches that are safe to delete
  slu each pull --ff-only    Run any git command in every repo
  slu trace --graph          A prettier log (git log itself is untouched)
  slu ilog                   Interactive TUI: browse commits and their diffs
  slu ibranch                Interactive TUI: browse branches and their commits
  slu update                 Update sluuz itself to the latest release
