Driver class for LALR text parsers.
This package contains an abstract LR parser and an abstract LALR parser. These abstract parsers lack the transition tables (an action table containing shift and reduce actions and a goto table), as well as reduction functions. The transition tables are usually automatically generated from a grammar definition, using Text_Parser_Generator.
You probably have no direct need for this package, and should use Structures_Grammar or Text_Parser_BNF to define a grammar and Text_Parser_Generator to generate a parser.
