The OATS package is a set of Java classes that assist in the design by test plans that utilize orthogonal arrays to select testcases. 

The distribution includes the OATS package plus a set of orthogonal array files. These arrays are named to identify the contents of the array. L3x2 indicates an array that supports the three factors, each with 2 levels per factor. This set of files is by no means exhaustive. 

The distribution includes the following files:

oats directory
	README - this file

	lib directory
	   oats directory
		GUIOrthogonalArray.class
		GUIMappedArray.class
		OrthogonalArray.class
		MappedArray.class
		tool.class
	   javabook2 directory
		*.class files for a number of files

	arrays directory
		Files named L*x*.oa which contain the orthogonal arrays

	doc directory
		JavaDoc files for the classes

	bin directory
		Batch file for the tool named oats.bat
