//    parser.[h,cc] -- table-driver LL(1) parser
//
//    Parsing and error correction tables are created by the program
//    makeparse.  The parsing tables are linked into the compiler in from the
//    file parsetab.cc.
//
//    The parser is a heavily-modified version of code originally written
//    by Jon Mauney.
