-# baserepo
+# pt / libpt
 
+`pt` stands for either one of "personal tool", "plex tool", "pete" or something among those lines.
+It is a collection of tools that i might or might not use. The intended purpose of this repo is that
+I program whatever i feel is worth having in a personal thing into it, then use it as either a lib,
+crate, python module or executable.
+
+Let's see if I make it a bloated mess or stop committing after 30 hello worlds.
+
+#### But the name `pt` / `libpt` already exists!
+So what? I don't care. Besides, there is not enough names to name everything unique.

+//! # A specialized Logger for [`libpt`](crate)
+//!
+//! For the library version, only the basic [`log`](crate::log) is used, so that it is possible for
+//! the end user to use the [`log`](crate::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 [`libpt`], but is still just as usable in other contexts.
+//!
+//! ## Technologies used for logging:
+//! - [`log`](crate::log): base logging crate
+//! - [`env_logger`](crate::env_logger): used for the executable
