Description: Translates a BNF (Backus-Naur Form) specification of a
        context-free language into an R grammar object which consists
        of the start symbol, the symbol table, the production table,
        and a short production table. The short production table is
        non-recursive. The grammar object contains the file name from
        which it was generated (without a path). In addition, it
        provides functions to determine the type of a symbol
        (isTerminal() and isNonterminal()) and functions to access the
        production table (rules() and derives()). For the BNF
        specification, see Backus, John et al. (1962) "Revised Report
        on the Algorithmic Language ALGOL 60". (ALGOL60 standards page
        <http://www.algol60.org/2standards.htm>, html-edition
        <https://www.masswerk.at/algol60/report.htm>) A preprocessor
        for macros which expand to standard BNF is included. The
        grammar compiler is an extension of the APL2 implementation in
        Geyer-Schulz, Andreas (1997, ISBN:978-3-7908-0830-X).
