//!
//! > **`cargo-rx` is a simple, modern *R*unner for *Ex*amples in a Cargo project.**
//!
//! A fuzzy finder tool which extends [Cargo] to allow you to easily search and run examples
//! from the command line.
//!
//! This crate provides a single executable: `rx`.
//!
//! [Cargo]: http://doc.crates.io/
//!
//!
//! <br>
//!
//! ## Demo
//!
//! [![rx demo](https://asciinema.org/a/483363.svg)](https://asciinema.org/a/483363)
//!
//! Basically anywhere you would use `cargo run --example` in a Rust project, try `rx` instead.
//!
//! ## Install
//!
//! Ensure that you have a fairly recent version of [rust/cargo] installed. Then, run:
//!
//! [rust/cargo]: https://doc.rust-lang.org/cargo/getting-started/installation.html
//! ```shell
//! $ cargo install cargo-rx
//! ```
//! *Compiler support: requires rustc 1.58+*
//!
//! ### Windows
//!
//! Note that on a *Windows* environment, you will also need to have [fzf installed]
//! and available in your *$PATH* variable.
//!
//! An easy way to install `fzf` is via [Chocolatey]:
//!
//! ```console
//! choco install fzf
//! ```
//!
//! There is currently a [feature request] open on `skim` which proposes adding
//! support for Windows, but this has not been currently implemented yet --
//! thus, the `fzf` tool serves as a stand-in alternative for now.
//!
//! [fzf installed]: https://github.com/junegunn/fzf#windows
//! [Chocolatey]: https://chocolatey.org/packages/fzf
//! [feature request]: https://github.com/lotabout/skim/issues/293
//!
//! ## Usage
//!
//! Once in a Cargo project with an `examples/` folder, run:
//!
//! ```console
//! $ rx
//! ```
//!
//! If you want to run a specific example, you can alternatively do that as well:
//!
//! ```console
//! $ rx my_example -- --my-arg "argument to pass in to example"
//! ```
//!
//! ## Examples
//!
//! You can check out sample usage of this crate in the [examples/](https://github.com/rnag/cargo-rx/tree/main/examples)
//! folder in the project repo on GitHub.
//!
//! ## Readme Docs
//!
//! You can find the crate's readme documentation on the
//! [crates.io] page, or alternatively in the [`README.md`] file on the GitHub project repo.
//!
