Sync Previous Module Files

This script helps you sync files from your previous module to the current module.
It copies files specified in 'files_to_sync.txt' from the source directory to the destination directory.

Usage: python sync_previous_module.py <source_directory> <destination_directory>

Examples:
    python sync_previous_module.py ./my-awesome-module-2 ./my-awesome-module-3
    python sync_previous_module.py ~/assignments/Module-2-unicorn_ninja ~/assignments/Module-3-unicorn_ninja
