 1// Package piglatindemo is a small gnoweb demo of the Pig Latin translator
 2// provided by the [p/moul/x/daily/piglatin](/p/moul/x/daily/piglatin/v0)
 3// library: it renders the rules, a gallery of worked examples, and an
 4// interactive sentence translator.
 5//
 6// It contains no translation logic of its own — everything comes from
 7// `piglatin.Translate` and `piglatin.TranslateToken`.
