The short production table is\nnon-recursive. The grammar object contains the file name from\nwhich it was generated (without a path). In addition, it\nprovides functions to determine the type of a symbol\n(isTerminal() and isNonterminal()) and functions to access the\nproduction table (rules() and derives()). For the BNF\nspecification, see Backus, John et al. (1962) \"Revised Report\non the Algorithmic Language ALGOL 60\". (ALGOL60 standards page\n, html-edition\n) A preprocessor\nfor macros which expand to standard BNF is included. The\ngrammar compiler is an extension of the APL2 implementation in\nGeyer-Schulz, Andreas (1997, ISBN:978-3-7908-0830-X).", "License": "MIT + file LICENSE", "URL":
