------------------------- Synopsis ------------------------

   Synopsis   yacc [options] yacc-file[.y] [output-file[.pas]]

   Options

   -v  "Verbose:" Yacc generates a readable description of the generated
       parser, written to yacc-file with new extension .lst.

   -d  "Debug:" Yacc generates parser with debugging output.

   Description

   This is a reimplementation of the popular UNIX compiler generator
   Yacc for MS-DOS and Turbo Pascal.

   Differences from UNIX Yacc:

   - Produces output code for Turbo Pascal, rather than for C.

   - Does not support %union definitions. Instead, a value type is declared
     by specifying the type identifier *itself* as the tag of a %token
     or %type definition. Yacc will automatically generate an appropriate
     yylval variable of a variant record type (YYSType) which is capable of
     holding values of any of the types used in %token and %type.

     Type checking is *very* strict. If you use type definitions, then
     any symbol referred to in an action *must* have a type introduced
     in a type definition. Either the symbol must have been assigned a
     type in the definitions section, or the $<type-identifier> notation
     must be used. The syntax of the %type definition has been changed
     slightly to allow definitions of the form
       %type <type-identifier>
     (omitting the nonterminals) which may be used to declare types which
     are not assigned to any grammar symbol, but are used with the
     $<...> construct.

   - The parse tables constructed by this Yacc version are slightly greater
     than those constructed by UNIX Yacc, since a reduce action will only be
     chosen as the default action if it is the *only* action in the state.
     In difference, UNIX Yacc chooses a reduce action as the default action
     whenever it is the only *reduce* action of the state (even if there are
     other shift actions).

     This solves a bug in UNIX Yacc that makes the generated parser start
     error recovery too late with certain types of error productions (see
     also Schreiner/Friedman, "Introduction to compiler construction with
     UNIX," 1985). Also, errors will be caught sooner in most cases where
     standard Yacc would carry out an additional (default) reduction before
     detecting the error.
