 223 wxWizard is the central class for implementing 'wizard-like'
 224 dialogs. These dialogs are mostly familiar to Windows users and are
 225 nothing else but a sequence of 'pages' each of them displayed inside a
 226 dialog which has the buttons to pass to the next (and previous) pages.
 227 <p>
 228 The wizards are typically used to decompose a complex dialog into
 229 several simple steps and are mainly useful to the novice users, hence
 230 it is important to keep them as simple as possible.
