   3 PIN CHannels - a simple drop-in replacement for `nix-channel --update`.

   5 Example usage, being invoked on the example "channels" file included here:
   6
   7     $ python3 pinch.py pin channels
   8     $ python3 pinch.py update channels

  28 The second "update" command applies these changes to your nix channels, like `nix-channel --update` does.

  30 Advantages over nix-channel:
  31
  32     * Deploy the exact same channel content to multiple machines.
  33     * Store your pin file in revision control for more powerful rollback mechanism than `nix-channel --rollback`.
  34     * Chanel contents are verified by hash before being installed.
