//! A file watcher on its own thread, a remote watch loop, a cache that could
//! not be written, a start that fell back to yesterday's configuration: each
//! reports and carries on. With the `tracing` feature they become proper
//! events; without it, stderr — which is the right default for a library that
//! must not choose a logging framework for its users.
