The document describes a batch event uploader tool that allows users to upload multiple calendar events using a CSV file format. The tool supports Create, Update, and Cancel commands to automate adding, modifying, and removing calendar events. Events are assigned unique identifiers (UIDs) that can then be referenced in the CSV file for updating or cancelling specific events. The system processes the CSV files and commands, generates calendar invites, and notifies attendees of any changes to events. The tool aims to emulate Calendarsnack's existing workflow for batch calendar management and automation.
