R parser generation system.
CUP is designed to fill the same role as the well known YACC parser
generator system, but is written in and operates entirely with Java code 
rather than C or C++.  Additional details on the operation of the system can 
be found in the parser generator and runtime source code.  See the CUP
home page below for access to the API documentation for the system and its
runtime.</p><p>

This document covers version 0.11b of the system.  Check the CUP home
