description         Backtracking LALR(1) parser generator
long_description    Kelbt generates backtracking LALR(1) parsers. \
                    Where traditional LALR(1) parser generators \
                    require static resolution of shift/reduce \
                    conflicts, Kelbt generates parsers that handle \
                    conflicts by backtracking at runtime. Kelbt is \
                    able to generate a parser for any context-free \
                    grammar that is free of hidden left recursion.
