Defines an extensible XML-based patching system that allows applying byte-level modifications to game binaries. Uses a clean separation between patch definition (XML) and application logic, supporting multiple data types (byte, bytes16, utf8, etc.) with TitleID-based targeting. The design allows new patch types to be added without modifying core logic.

Provides a robust inter-process communication mechanism between the loader and daemon using Unix domain sockets. Implements request/response patterns with proper serialization and error handling. The component is self-contained and could be reused in other projects needing lightweight IPC.

While this is a vendored FUSE header, the way it's integrated into the daemon shows good abstraction layers. The daemon uses FUSE to provide virtual filesystem capabilities for mounting network shares and managing game installations, demonstrating a clean separation between filesystem operations and application logic.

A well-designed INI parser with line number preservation and error handling. Supports both string and numeric values, section handling, and provides a clean API for configuration management. The implementation is self-contained and could be easily extracted for use in other projects.
