13 | * The revision walking API offers functions to build a list of revisions | |
14 | * and then iterate over that list. | |
15 | * | |
16 | * Calling sequence | |
17 | * ---------------- | |
18 | * | |
19 | * The walking API has a given calling sequence: first you need to initialize | |
20 | * a rev_info structure, then add revisions to control what kind of revision | |
21 | * list do you want to get, finally you can iterate over the revision list. | |
22 | * | |
