overview = """\
This demo shows a collection of classes that were designed to operate
together and provide a tree control with additional columns for each
item.  The classes are wxRemotelyScrolledTreeCtrl, wxTreeCompanionWindow,
wxThinSplitterWindow, and wxSplitterScrolledWindow, some of which may
also be useful by themselves.
