70  *b Description:
71  **
72  ** This function tells DI-Guy that it should use the OpenAL API for
73  ** playing back sounds.
74  **
75  ** This function must be called before a scenario is created.

77  ** This function must be called after the main DI-Guy initialize call
78  ** (e.g., diguy_ogl_initialize()).

85  **
86  *e bdiSoundInitOpenAL init;
87  *e
88  *e diguy_ogl_initialize(NULL);
89  *e diguy_script_perl_initialize();
