+// 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.
