45 Configuration to write to /etc/gitconfig. A list can also be
46 specified to keep the configuration in order. For example, setting
47 `config` to `[ { foo.x = 42; } { bar.y = 42; }]` will put the `foo`
48 section before the `bar` section unlike the default alphabetical
49 order, which can be helpful for sections such as `include` and
50 `includeIf`. See the CONFIGURATION FILE section of git-config(1) for
51 more information.
