# When this script runs:
#   - cargo/food/, cargo/water/, cargo/tools/ already exist
#   - cargo/food/manifest.txt exists (empty)
#   - inbox/ contains files with prefixes:
#       food-apple.txt, food-bread.txt
#       water-bottle.txt, water-canteen.txt
#       tool-wrench.txt, tool-hammer.txt
#
# Your script must:
#   1. Move all food-*.txt files into cargo/food/
#   2. Move all water-*.txt files into cargo/water/
#   3. Move all tool-*.txt files into cargo/tools/
#   4. Copy cargo/food/manifest.txt to cargo/food/manifest.backup
#
# Tools: mv, cp
