    <title>Basic Use</title>

    <para>
	&app; can only be used to create relatively simple dialogs, but is especially useful
	when used in scripts. When a user has completed an action requested of them, and the 
	dialog closes, &app; prints any text specific to the dialog to standard error and
	an exit code is returned. Information about what text is printed to standard error will be 
	detailed in the individual dialog sections.
    </para>

    <para>
	When using &app;, make sure that any arguments to the command line options are surrounded by
	a set of quotes ' ' or " " as in <command>&app; --calendar --dialog-title="Holiday Planner"
	</command>, for example. If you do not use quotes, then it is likely that you will get
	unexpected results.
    </para>

    <para>
    	For some of the dialogs, &app; supports the use of keyboard mnemonics. This allows you to
	use an '_' before the letter you want the mnemonic for, as in "_Please choose a name:", for
	example.
    </para>

    <para>
    	The following exit codes are observed by &app;:
