//! # S3 TUI Application
//!
//! This crate provides a simple `S3` client for managing your resources in s3 buckets.
//! `s3tui` is a powerful terminal-based application that enables seamless file transfers between
//! your local machine and multiple AWS S3 accounts. 
//! Crafted with the `ratatui` Rust TUI framework, `s3tui` provides a robust user interface for managing 
//! uploads and downloads simultaneously in both directions, 
//! enhancing your productivity with `S3` services.
