//!
//! - Repository: <https://bitbucket.org/haibison/rgb-io>
//! - License: Nice License 1.0.0 _(see LICENSE file at root directory of `master` branch)_
//! - _This project follows [Semantic Versioning 2.0.0]_
//!
//! ## Features
//!
//! This is a simple program, which lets you type in RGB color(s) in hexadecimal format, then prints sample color(s) to standard ouput.
//!
//! You can run the program with `help` command for more details.
//!
//! ## Building from source or installing via Cargo

//!
//! `bin` feature contains a binary which uses some dependencies.
//!
//! ### Building from source:
//!
//! ```shell
//! ~> # Clone a specific version via tag name
//! ~> git clone --branch=x.y.z --depth=1 -- https://bitbucket.org/haibison/rgb-io rgb-io-x.y.z/
//! ~> cd rgb-io-x.y.z/
//! ~> cargo build --release --features=bin
//! ```
//!
//! ### Installing via Cargo:
//!
//! ```shell
//! ~> cargo install rgb-io --version=x.y.z --features=bin
//! ```
