# Does like `maintainers/scripts/debian-patches.sh`, but specialized for
# grub1 patches, and using the new salsa service.

# Most common usage: `pkgs/tools/misc/grub/grub1.patches.sh pkgs/tools/misc/grub/grub1.patches.nix`
# That is, after updating the script with the new list from the series file,
# removing (by commenting) patches as required.
