R.M.Allan, University of Canterbury, 1989.

To install Stress, the following two files must be filed in:

	Utilities necessary to the basic functioning of Stress,
	including browser indenting of classes, DecodingStreams, and
	modified 'growing' of Dictionaries.

Stress.St
---------
	The classes and methods of Stress itself.

The Birdsville example described in Chapter 6 of the thesis is also
provided.  The basic knowledge base is contained in 'Birdsville.stress';
additional facts for the trial system are contained in
'Birdsville.trial'.

The folder 'OtherUtilities' contains the other additions to the
standard image described in Appendix A of the thesis, these being
ChangeTrees, and VariableDictionaryInspectors.
