# Remove Ferryman from this machine.
#
# Deliberately conservative about three things, because getting any of them wrong
# is worse than leaving a file behind:
#
#   - Your OPERATOR IDENTITY is never deleted without --identity. It is sealed under a
#     password nothing else holds a copy of, and if you uninstall to reinstall you want
#     it to still be there afterwards. A disk cleaner deleting one is what taught us this.
#   - Your CHANNELS are never deleted. They are the coordination history for real work,
#     they live in your projects, and Syncthing would carry the deletion to every other
#     machine in the fleet.
#   - Nothing outside Ferryman's own directories is touched. Syncthing is not ours.

  --identity   also remove your operator identity and its spare copy.
               There is no undo except your 24-word recovery phrase.
  --dry-run    list what would be removed, remove nothing.
