 1// Package cowsaydemo is a small gnoweb demo of the cowsay renderer provided by
 2// the [p/moul/x/daily/cowsay](/p/moul/x/daily/cowsay/v0) library: it makes the
 3// ASCII cow say whatever you put in the path.
 4//
 5// It contains no rendering logic of its own — the art comes entirely from
 6// `cowsay.Say`.
