//! This test rig is a total hack to quickly exercise `src/driver.rs`.
//!
//! I should make it real, but I just want Codecov to stop complaining about
//! my test coverage. To re-use the `tex-outputs` test artifacts, the
//! ProcessingSessionBuilder will need to learn how to tell `xdvipdfmx` to
//! enable the reproducibility options used in the `tex-outputs` test rig.
