                      4: This directory contains source for a version of yacc needed by the Pascal
                      5: parser.  The differences between this yacc and a stadard version 6 yacc
                      6: are indicated in a comment in y1.c.
                      7: 
                      8: Note that the standard yacc parser will not work on the tables produced
                      9: by "eyacc" and also that these changes are really useful only with
                     10: a fairly large set of error recovery routines which are part of both
                     11: "pi" and "pxp".  The routines are language independent, but the method
                     12: will only work on languages which have some redundancy in them... it is
                     13: probably ill suited for C, but would work fine in ALGOL-60, ALGOL-W,
                     14: EUCLID, LIS, SP/K, PL/1, ALPHARD, CLU, ...

                     18: A paper describing the method used by eyacc will appear in August in the
                     19: SIGPLAN Boulder conference.

                     23: The eyacc in this directory has been modified to work for
                     24: version 7.  This involved syntax fixes and changing the I/O calls
                     25: to standard version 7 calls.
