 As the ``onecmd_plus_hooks`` name implies, there are a number of *hook* methods that can be defined in order to inject
 application-specific behavior at various points during the processing of a line of text entered by the user.  ``cmd2``
 increases the 2 hooks provided by ``cmd`` (**precmd** and **postcmd**) to 6 for greater flexibility.  Here are
 the various hook methods, presented in chronological order starting with the ones called earliest in the process.
