   3 Now that [flakes][https://nixos.wiki/wiki/Flakes] are more or less ready for
   4 general use, this is mostly of historical interest.

   9 PIN CHannels - a simple drop-in replacement for `nix-channel --update`.
  10
  11 Example usage, being invoked on the example "channels" file included here:
  12
  13     $ python3 pinch.py pin channels
  14     $ python3 pinch.py update channels
  15
  16
  17 The first "pin" command will add these fields to the file:

  20      channel_url = https://channels.nixos.org/nixos-20.03
  21      git_repo = https://github.com/NixOS/nixpkgs.git
  22      git_ref = nixos-20.03

  30      git_ref = master
  31     +release_name = nixos-hardware.git-1585241157-edb7199b5c4
  32     +git_revision = edb7199b5c4f1db34a7253d4cabf6cf690521a92

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