+%description
+BYACC/J is an extension of the Berkeley v 1.8 YACC-compatible parser generator.
+Standard YACC takes a YACC source file, and generates one or more C files from it,
+which if compiled properly, will produce a LALR-grammar parser.
+This is useful for expression parsing, interactive command parsing, and file reading.
+Many megabytes of YACC code have been written over the years.
+This is the standard YACC tool that is in use every day to produce C/C++ parsers.
+I have added a "-J" flag which will cause BYACC to generate Java source code, instead.
+So there finally is a YACC for Java now!
