# The Maker — build a cargo bay.
#
# When this script runs, a stale file `cargo-old.txt` is in your
# working directory. Your script must:
#
#   1. Create directories: cargo/food, cargo/water, cargo/tools
#   2. Create an empty file `manifest.txt` in each of those three rooms
#   3. Remove cargo-old.txt
#
# Tools: mkdir (use -p for nested), touch, rm

# Your code here.
