   1 About
   2 =====
   3
   4 `diff-hl-mode` provides IDE-like highlighting of `vc-diff` results on the left
   5 fringe of the current buffer.
   6
   7 Additionally, it defines and binds `diff-hl-diff-goto-hunk` and
   8 `diff-hl-revert-hunk`, to `C-x v =` and `C-x v n` respectively.
   9
  10 Since it uses the corresponding VC diff command, it's only accurate when the
  11 buffer is in saved state.
  12
  13 Tested with Git, Mercurial, and Bazaar. May work with other VC backends, too.
