Kelbt: Backtracking LR Parsing
Kelbt generates backtracking LALR(1) parsers. Whereas standard LALR(1) parser generators emit an error upon encountering a conflict in the parse tables, Kelbt forges onward, generating parsers which handle conflicts by backtracking at runtime. As Kelbt is able to generate a parser for any context-free grammar, it therefore implements a generalized parsing method.
