       bison - GNU Project parser generator (yacc replacement)

MO T<?>
       Bison is a parser generator in the style of yacc(1).  It should be
       upwardly compatible with input files designed for yacc.

       Input files should follow the yacc convention of ending in .y.  Unlike
       yacc, the generated files do not have fixed names, but instead use the
       prefix of the input file.  Moreover, if you need to put C++ code in the
       input file, you can end his name by a C++-like extension (.ypp or
       .y++), then bison will follow your extension to name the output file
       (.cpp or .c++).  For instance, a grammar description file named
       parse.yxx would produce the generated parser in a file named
       parse.tab.cxx, instead of yacc's y.tab.c or old Bison version's
       parse.tab.c.

       This description of the options that can be given to bison is adapted
       from the node Invocation in the bison.texi manual, which should be
       taken as authoritative.

       Bison supports both traditional single-letter options and mnemonic long
       option names.  Long option names are indicated with -- instead of -.
       Abbreviations for option names are allowed as long as they are unique.
       When a long option takes an argument, like --file-prefix, connect the
       option name and the argument with =.
