   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 Since it uses the corresponding VC diff command, it's only accurate when the
   8 buffer is in saved state.
   9
  10 Additionally, it defines and binds `diff-hl-diff-goto-hunk` and
  11 `diff-hl-revert-hunk`, to `C-x v =` and `C-x v n` respectively.
  12
  13 Tested with Git, Mercurial, and Bazaar. May work with other VC backends, too.
