Usage: cpmutil.sh package hash [-n|--dry-run] [-a|--all] [PACKAGE]...

Check the hash of a specific package or packages.
If a hash mismatch occurs, this script will update the package's hash.

Options:
    -n, --dry-run	Don't update the package's hash if it's a mismatch
    -a, --all       Operate on all packages in this project.

Note that this procedure will usually take a long time
depending on the number and size of dependencies.
