Just like ProgramName and DisplayName can already be customized via public vars in the cmd package, DefaultDir also looks like a perfect candidate to customize this way (and assembling the help text can then be done using {{.DefaultDir}}).
In addition, cli.HelpHeader and cli.HelpFooter are made public, so that they can be extended and overridden.
