Summary	Regions.st

	This directory contains one source code filein, Regions.st, and
seven data files: Africa.data, Asia.data, Europe.data, NorthAmerica.data,
SouthAmerica.data, SouthPacific.data, and USA.data.
	Regions.st defines a simple class of objects (Regions) that 
represent general named regions and may contain one or more boundaries
(Boundary). A simple graphical browser (RegionBrowser) is used to display
and interact with collections of regions (acquired from the data files).
	Regions.st defines the following classes: Boundary, Region,
RegionBrowser, RegionView, and RegionViewController. In addition, one
method is added to Point and one is added to ExternalReadStream.
	The data files were generated from public domain MacDraw files.
Each file contains one continent or area of the world. The USA.data file
contains the 50 United States as regions.
	Once you have filed in the Regions.st code, look at the class
methods under Region for further documentation. This will tell you how
to load in the data files. If you have the data files in your current
directory there's nothing more to do. If not, you will have to specify
the path.
	This is a new and improved version of a previous application I
did called usa.st. I generalized it to represent general named regions
and added more data files.

Enjoy!
