| 2 | * docproc is a simple preprocessor for the template files |
| 3 | * used as placeholders for the kernel internal documentation. |
| 4 | * docproc is used for documentation-frontend and |
| 5 | * dependency-generator. |
| 6 | * The two usages have in common that they require |
| 7 | * some knowledge of the .tmpl syntax, therefore they |
| 8 | * are kept together. |

| 21 | * dependency-generator: |
| 22 | * Scans the template file and list all files |
| 23 | * referenced in a format recognized by make. |
| 24 | * Usage: docproc depend file.tmpl |
| 25 | * Writes dependency information to stdout |
| 26 | * in the following format: |
