//! # Loader
//!
//! This module contains a loader for file section.
//! Following the common standard file format for executable files
//! [ELF (Executable and Linkable Format)](https://en.wikipedia.org/wiki/Executable_and_Linkable_Forma)
//!
//! It's used to charge a programme into the machine from a binary file (.guac files)
//!
//! Basic usage:
//!
//! ```
//! let args = Args::parse();
//! let mut machine = Machine::new(args.debug & 1 != 0, read_settings().unwrap());
//! let (loader, ptr) = loader::Loader::new(args.executable.as_str(), &mut machine, 0).expect("An error occured while parsing the program");
//! ```
