// Package cowsaydemo is a small gnoweb demo of the cowsay renderer provided by
// the [p/moul/x/daily/cowsay](/p/moul/x/daily/cowsay/v0) library: it makes the
// ASCII cow say whatever you put in the path.
//
// It contains no rendering logic of its own — the art comes entirely from
// `cowsay.Say`.
