Lines 137 to 146 in 6d68df1

	fn print_tldr_error() {
	eprintln!("Warning: No tldr archive found, so the documentation will not include examples.");
	eprintln!(
	"To include examples in the documentation, download the tldr archive and put it in the docs/ folder."
	);
	eprintln!();
	eprintln!(
	" curl -L https://github.com/tldr-pages/tldr/releases/latest/download/tldr.zip -o docs/tldr.zip"
	);
	eprintln!();

Calling this for all utils pollutes the build log. No need to show it 100+ times.
