+//! Custom logging macros, with the same names as `log` crate's `trace!`, `debug!`, `info!`, `warn!`, `error!`,
+//! but different behavior: automatically prepend `file!()` information to the message.
+//!
+//! # Usage
+//! ```ignore
+//! trace!("value = {}", x);
+//! debug!("something happened");
+//! info!("user {} logged in", username);
+//! warn!("disk space low: {} GB", free);
+//! error!("failed to open file: {}", path);
+//! ```
+//!
+//! Expands to:
+//! ```ignore
+//! ::log::trace!("[{}]: {}", file!(), format!("value = {}", x));
+//! ::log::debug!("[{}]: {}", file!(), format!("something happened"));
+//! ...
+//! ```
