Berkeley yacc parser generator

Berkeley yacc is a parser generator utility that reads a grammar specification from a file and generates an LR(1) parser for it. The parsers consist of a set of LALR(1) parsing tables and a driver routine written in the C programming language. It has a public domain license which includes the generated C.

This package is configured with backtracking enable which makes it reasonably compatible with GNU bison.

Note that for better compatibility with bison, byacc supports the --defines=<defines_file> and --output=<output_file> options as alternatives for -H <defines_file> and -o <output_file>. For example:
