Bison is a parser generator, a replacement for yacc. Bison generates a program that analyzes the structure of a text file.
Installed programs: bison and yacc
Installed library: liby.a
bison generates, from a series of rules, a program for analyzing the structure of text files. Bison is a replacement for yacc (Yet Another Compiler Compiler).
yacc is a wrapper for bison, meant for programs that still call yacc instead of bison. It calls bison with the -y option.
liby.a is the Yacc library containing implementations of Yacc-compatible yyerror and main functions. This library is normally not very useful, but POSIX requires it.
