    - Addon Interfaces Library: Overview
      The Addon Interfaces (AOI) library (libaoi.so) provides a framework for developing and using addon interfaces.
    - Using Addon Resources
    - Predefined Interfaces
      - Recognized interfaces
        The library recognizes special interfaces for setting up and cleaning up DLLs, allowing DLLs to expose strings to applications, and assigning names to controls. A control is a programming representation of the interfaces implemented by an addon DLL or defined statically in the code.
