New Bonnie configurations can be created very quickly and efficiently with `bonnie -i`. This uses a pre-programmed default normally, but it can also be instructed to use a template by running `bonnie -i --template /path/to/your/template/file` instead. These templates are NOT checked for their validity, so you can put placeholders or whatever you want in there.

You can also set a global template at `~/.bonnie/template.toml` (changeable with the `BONNIE_TEMPLATE` environment variable), which will be used if `--template` isn't set. This essentially allows global file configurations (such as a default shell), while still maintaining the atomicity and portability of individual configuration files.
