   The RL files contain code for defining relational grammars
   and using them in a bottom-up parser to recognise and/or parse
   expressions in Relational Languages.

   The approach is a simplification of that described in
   Wittenburg, Weitzman, and Talley (1991), Unification-Based
   Grammars and Tabular Parsing for Graphical Languages, Journal
   of Visual Languages and Computing 2:347-370.  This code is
   designed to support the definition and parsing of Relational
   Languages, which are characterised as sets of objects standing
   in user-defined relations.

   Correctness and completeness is independent of the order in
   which the input is given to the parser.  Data to be parsed can
   be in many forms as long as an interface is supported for
   queries and predicates for the relations used in grammar
   productions.

   To date, this software has been used to parse recursive
   pen-based input such as math expressions and flow charts; to
   check for data integrity and design conformance in
   databases; to automatically generate constraints in
   drag-and-drop style graphical interfaces; and to generate
   graphical displays by parsing relational data and generating
   output code.
