   2
   3 A radio button item is a button which usually denotes one of several mutually
   4 exclusive options. It has a text label next to a (usually) round button.
   5
   6 You can create a group of mutually-exclusive radio buttons by specifying {\tt wxRB\_GROUP} for
   7 the first in the group. The group ends when another radio button group is created, or there are no more radio buttons.
