/*
 * This is a "yacc" specification of the syntax of RLISP. It is used
 * to provide a (symbolic-mode) RLISP to Lisp translator that can be
 * made freely available without reference to anybody apart from
 * myself!  The Lisp dialect generated is Standard Lisp and in all reality
 * I intend it to be for use with CSL (my own Lisp). I am putting in
 * a switch that causes generation of something a bit more like Common
 * Lisp but please do not expect this to be fully sorted out and
 * suitable for use with full Common Lisp: again it is tuned to my own
 * private purposes...
 *
 * I will think about making this work with Bison as wall as Yacc but
 * maybe I prefer the licence terms associated with Yacc. But it is quite
 * certain that if you receive this code and can make it work with Bison
 * you can use it internally: the only issues are to do with distribution,
 * and if you are careful to use a sufficiently modern release of Bison
 * its skeleton code may be distributed without bad license consequences.
 *
 * Usage:
 *      r2l -common -rights -Dname=val source1.red ... sourcen.red dest.lsp
