2 | * We put all the git config variables in this same object | |
3 | * file, so that programs can link against the config parser | |
4 | * without having to link against all the rest of git. | |
5 | * | |
6 | * In particular, no need to bring in libz etc unless needed, | |
7 | * even if you might want to know where the git directory etc | |
8 | * are. | |
