yacc[options]file
Given a file containing context-free grammar,
convert file into tables for subsequent parsing
and send output to y.tab.c. This command name stands for
yet another compiler-compiler.
See also lex and the Nutshell Handbook lex & yacc.
Generate y.tab.h, producing #define statements that relate yacc's token codes to the token names declared by the user.
Exclude #line constructs from code produced in y.tab.c. (Use after debugging is complete.)
cPlace version information about yacc in y.tab.c (if c = y)
or suppress information (if c = n, the default).
Compile runtime debugging code by default.
Generate y.output, a file containing diagnostics and notes about the parsing tables.
Print the version of yacc on standard error.
