-//! # [Ratatui] Panic Hook example
-//!
-//! The latest version of this example is available in the [examples] folder in the repository.
-//!
-//! Please note that the examples are designed to be run against the `main` branch of the Github
-//! repository. This means that you may not be able to compile with the latest release version on
-//! crates.io, or the one that you have installed locally.
-//!
-//! See the [examples readme] for more information on finding examples that match the version of the
-//! library you are using.

-//! [examples readme]: https://github.com/ratatui/ratatui/blob/main/examples/README.md
-//!
-//! Prior to Ratatui 0.28.1, a panic hook had to be manually set up to ensure that the terminal was
-//! reset when a panic occurred. This was necessary because a panic would interrupt the normal
-//! control flow and leave the terminal in a distorted state.
-//!
-//! Starting with Ratatui 0.28.1, the panic hook is automatically set up by the new `ratatui::init`
-//! function, so you no longer need to manually set up the panic hook. This example now demonstrates
-//! how the panic hook acts when it is enabled by default.
-//!
-//! When exiting normally or when handling `Result::Err`, we can reset the terminal manually at the
-//! end of `main` just before we print the error.
-//!
-//! Because a panic interrupts the normal control flow, manually resetting the terminal at the end
-//! of `main` won't do us any good. Instead, we need to make sure to set up a panic hook that first
-//! resets the terminal before handling the panic. This both reuses the standard panic hook to
-//! ensure a consistent panic handling UX and properly resets the terminal to not distort the
-//! output.
-//!
-//! That's why this example is set up to show both situations, with and without the panic hook, to
-//! see the difference.
-//!
-//! For more information on how to set this up manually, see the [Color Eyre recipe] in the Ratatui
-//! website.
