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.
+dialogs are mostly familiar to Windows users and are nothing other than a
+sequence of `pages', each displayed inside a dialog which has the
+buttons to navigate to the next (and previous) pages.
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.

\helpref{Create}{wxwizardcreate} function. Then you should add all pages you
want the wizard to show and call \helpref{RunWizard}{wxwizardrunwizard}.

if the size required by the new page is bigger than the previously set one.
