                      9: This directory contains source for a version of yacc needed by the Pascal
                     10: parser.  The differences between this yacc and a stadard version 6 yacc
                     11: are indicated in a comment in y1.c.
                     12: 
                     13: Note that the standard yacc parser will not work on the tables produced
                     14: by "eyacc" and also that these changes are really useful only with
                     15: a fairly large set of error recovery routines which are part of both
                     16: "pi" and "pxp".  The routines are language independent, but the method
                     17: will only work on languages which have some redundancy in them... it is
                     18: probably ill suited for C, but would work fine in ALGOL-60, ALGOL-W,

                     23: A paper describing the method used by eyacc will appear in August in the
