<h2><center>wxWizard</center></h2>

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