| 50 | * Use: Locates a user-configurable resource file. The search order |

| 52 | * and (b) whether the use of Acorn's `Choices' system is |
| 53 | * enabled. |
| 54 | * |
| 55 | * The search order is as follows: |
| 56 | * |
| 57 | * * Choices:appName.leaf / <Choices$Write>.appName.leaf |
| 58 | * * res_find(leaf) |
| 59 | * |
| 60 | * (i.e. it looks in the `Choices' structure first, and if that |
| 61 | * fails, it will use res_find). |
