NAME		yacc -- yet another compiler compiler

SYNOPSIS	_____________/crp/scj/yacc  [ <grammar ]
.sp
.ti 0
DESCRIPTION	Yacc converts a context-free grammar into a set of
tables for a simple automaton which executes an LR(1) parsing
algorithm.
The tables are provided in readable form on the standard output
and in b-compiler format on file actn.b; the program
/crp/scj/bpar.b will parse strings using the actn.b file.
.sp
If your grammar is too big for yacc, you may
try /crp/scj/bigyacc,
some of whose size limits are
larger, and others smaller.

FILES		actn.b  	output tables
.br
actn.tmp	temporary storage

Note that these files are created in the invoker's
directory.
The file actn.tmp is only created by /crp/scj/bigyacc
(see above).

BUGS		The maximum number of terminal and non-terminal symbols

undoubtedly other bugs too.
