=head1 DESCRIPTION

wizards is a layer built on top of the interactive layer that do proper
backward/forward stepping for us.

A step is made up of a name/description, a list of interactive fields (see
interactive documentation), a "complete", "pre" and "post" callbacks, an help
id, ...

The "pre" callback is run first. Its only argument is the actual step hash.

Then, if the "name" fiels is a code reference, that callback is run and its
actual result is used as the description of the step.

At this stage, the interactive layer is used to display the actual step.

The "post" callback is only run if the user has steped forward.


Alternatively, you can call safe_process() rather than process().
safe_process() will handle for you the "wizcancel" exception while running the
wizard.  Actually, it should be used everywhere but where the wizard is not the
main path (eg "mail alert wizard" in logdrake, ...), ie when you may need to do
extra exception managment such as destroying the wizard window and the like.
