The script is a website mirroring tool that creates a directory structure under a "sites" folder, organizing downloaded files by type (e.g., images, CSS). It modifies HTML links to point to local files and generates a ZIP archive containing all downloaded content. The process includes making HTTP requests, saving files, and processing HTML tags to identify file references. The main function takes a URL as input and handles the mirroring process, saving the modified HTML and creating the ZIP file.
