+ An expo is a way of presenting and collecting information from the
+ user. It consists of a collection of 'scenes' of which only one is
+ presented at a time. An expo is typically used to show a boot menu
+ and allow settings to be changed.
+
+ The expo can be presented in graphics form using a vidconsole, or in
+ text form on a serial console.
