10 | * The config API gives callers a way to access Git configuration files | |
11 | * (and files which have the same syntax). | |
12 | * | |
13 | * General Usage | |
14 | * ------------- | |
15 | * | |
16 | * Config files are parsed linearly, and each variable found is passed to a | |
17 | * caller-provided callback function. The callback function is responsible | |
18 | * for any actions to be taken on the config option, and is free to ignore | |
19 | * some options. It is not uncommon for the configuration to be parsed | |
20 | * several times during the run of a Git program, with different callbacks | |
21 | * picking out different variables useful to themselves. | |
