// Package pretty provides pretty-printing for Go values. This is
// useful during debugging, to avoid wrapping long output lines in
// the terminal.
//
// It provides a function, Formatter, that can be used with any
// function that accepts a format string. It also provides
// convenience wrappers for functions in packages fmt and log.
