* For things you do not want rustfmt to mangle, use one of
```rust
#[rustfmt_skip]
#[cfg_attr(rustfmt, rustfmt_skip)]
#[rustfmt_skip] // requires nightly and #![feature(custom_attribute)] in crate root
#[cfg_attr(rustfmt, rustfmt_skip)] // works in stable
```
* When you run rustfmt, place a file named rustfmt.toml in target file
directory or its parents to override the default settings of rustfmt.
