+//! # A specialized Logger for [`pt`](crate)
+//!
+//! For the library version, only the basic [`log`] is used, so that it is possible for
+//! the end user to use the [`log`] frontend they desire.
+//!
+//! I did however decide to create a [`Logger`] struct. This struct is mainly intended to be used
+//! with the python module of [`pt`](crate), but is still just as usable in other contexts.
+//!
+//! ## Technologies used for logging:
+//! - [`log`]: base logging crate
+//! - [`env_logger`]: used for the executable
