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