## Non-macro code generators
When using `quote` in a build.rs or main.rs and writing the output out to a
file, consider having the code generator pass the tokens through [rustfmt]
before writing (either by shelling out to the `rustfmt` binary or by pulling in
the `rustfmt` library as a dependency). This way if an error occurs in the
generated code it is convenient for a human to read and debug.
