user.email::
Your email address to be recorded in any newly created commits.
Can be overridden by the `GIT_AUTHOR_EMAIL`, `GIT_COMMITTER_EMAIL`, and
`EMAIL` environment variables. See linkgit:git-commit-tree[1].
user.name::
Your full name to be recorded in any newly created commits.
Can be overridden by the `GIT_AUTHOR_NAME` and `GIT_COMMITTER_NAME`
environment variables. See linkgit:git-commit-tree[1].
user.email::
author.name::
author.email::
committer.name::
committer.email::
The `user.name` and `user.email` variables determine what ends
up in the `author` and `committer` field of commit
objects.
If you need the `author` or `committer` to be different, the
`author.name`, `author.email`, `committer.name` or
`committer.email` variables can be set.
Also, all of these can be overridden by the `GIT_AUTHOR_NAME`,
`GIT_AUTHOR_EMAIL`, `GIT_COMMITTER_NAME`,
`GIT_COMMITTER_EMAIL` and `EMAIL` environment variables.
See linkgit:git-commit-tree[1] for more information.
user.useConfigOnly::
Instruct Git to avoid trying to guess defaults for `user.email`
