overview = """\
This class allows you to use the system font selection dialog 
from within your program. Generally speaking, this allows you
to select a font by its name, font size, and weight, and 
on some systems such things as strikethrough and underline.

As with other dialogs used in wxPython, it is important to
use the class' methods to extract the information you need
about the font <b>before</b> you destroy the dialog. Failure
to observe this almost always leads to a program failure of 
some sort, often ugly.

This demo serves two purposes; it shows how to use the dialog
to GET font information from the user, but also shows how
to APPLY that information once you get it.
