miruga27 | 0:dda4f4550403 | 29 | * |

miruga27 | 0:dda4f4550403 | 34 | * supported or applicable on any given platform, but they provide |
miruga27 | 0:dda4f4550403 | 35 | * a way for an application or user to give the library a hint as |
miruga27 | 0:dda4f4550403 | 36 | * to how they would like the library to work. |
