	{
		use {
			::std::io::IsTerminal,
			::tracing_subscriber::layer::{Layer, SubscriberExt},
		};

		let out = ::std::io::stdout();
		let use_ansi = out.is_terminal();
		let use_symbols = out.is_terminal();

		::tracing::subscriber::set_global_default(
			::tracing_subscriber::registry().with(
				::tracing_fancytree::FancyTree::new(out, use_ansi, use_symbols),
			),
