Providing a CLI
***************

The "beets.ui" module houses interactions with the user via a
terminal, the Command-Line Interface. The main function is called when
the user types beet on the command line. The CLI functionality is
organized into commands, some of which are built-in and some of which
are provided by plugins. The built-in commands are all implemented in
the "beets.ui.commands" submodule.
