// Package msg is a tool for handling commandline output based on
// flags for quiet, verbose, and debug modes. The default is to
// have all modes disabled.
//
// The Qprint messages will only output messages if quiet mode is
// disabled
// The Vprint messages will only output messages if verbose mode
// is enabled.
// The Dprint messages will only output messages if debug mode
// is enabled.
