+# These aliases should not be used within nixpkgs, but exist to improve
+# backward compatibility in projects outside of nixpkgs. See the
+# documentation for the `allowAliases` option for more background.

+# A script to convert old aliases to throws and remove old
+# throws can be found in './maintainers/scripts/remove-old-aliases.py'.
+
+# Add 'preserve, reason: reason why' after the date if the alias should not be removed.
+# Try to keep them to a minimum.
+# valid examples of what to preserve:
+#   distro aliases such as:
+#     debian-package-name -> nixos-package-name
+
+# pkgs is provided to allow packages to be moved out of the darwin attrset.
