# Usage:
# -- Dry run mode
# ./npm-link.sh --dry-run

# -- Link all packages (except those ending with "-vanilla") or specific packages
# ./npm-link.sh --link
# ./npm-link.sh --link <project-directory-name1> <project-directory-name2> ...
# eg. ./npm-link.sh --link lit-node-client another-project

# -- Unlink all packages (except those ending with "-vanilla") or specific packages
# ./npm-link.sh --unlink
# ./npm-link.sh --unlink <project-directory-name1> <project-directory-name2> ...

# -- Specify base directory
# ./npm-link.sh --dir <base-directory-path>

# Define the base directory
