Comp.compilers: yaccviso 1.0 - a tool for visualizing yacc/bison grammars YaccViso is a tool for visualizing dependencies of non terminal and
terminal symbols in a yacc grammar. If you do not know what yacc is
then you probably won't need YaccViso. It is thus a tool specifically
designed for people who write compilers with yacc who work on large
grammar files.
