## Project Overview

This project provides PHP tools to parse, modify, and generate ProPresenter 7 files:

- **Songs** (`.pro`) — Presentation files containing lyrics with groups, slides, arrangements, and translations
- **Playlists** (`.proplaylist`) — ZIP archives containing playlist metadata and embedded song files
- **Bundles** (`.probundle`) — ZIP archives containing a single presentation with embedded media assets
- **Global library files** — `Macros`, `Labels`, `Groups`, `ClearGroups`, `CCLI`, `Messages`, `Timers`, `Stage`, `Workspace`, `Props`, `TestPatterns`, `Calendar`, `KeyMappings`, `CommunicationDevices` (JSON)
- **Theme folders** — directory with a `Theme` protobuf file plus an `Assets/` subdirectory of media
