          README for the ia libraries

This directory contains the following five libraries 

ia_math   -- version 0.1beta1, 10/97
             copyrighted using GNU Library General Public License
            
ia_parser -- version 0.1beta1, 10/97
             copyrighted using GNU Library General Public License
           
ia_solver -- version 0.1beta1, 10/97
             copyrighted using GNU Library General Public License
           

JLex      -- copyrighted in 1996 by Elliot Berk (see JLex/Main.java)

CUP       -- written by Scott E Hudson, 
             modified by Frank Flannery, Scott Ananian, Dan Wang
                 under the supervision of Andrew W Appel 9/97

and two files:

ia.tar.gz -- the gzipped, tarred version of this directory

IAsolver.html -- the html file calling the IAsolver applet

****************************************************************

I have found no copyright notice or licensing information for
java_cup, so you should probably get CUP directly from Princeton
at the following URL:
  http://www.cs.princeton.edu/~appel/modern/java/CUP/
I've included a courtesy copy in this version, but it will be removed
when the applet site becomes inaccessible.
****************************************************************

The ia_* libraries contain classes and methods for interval arithmetic. 

  ia_math   -- is a pure interval arithmetic package.

  ia_parser -- contains parsing and narrowing methods for 
               interval arithmetic expressions
  ia_solver -- has a GUI for ia_parser
