-/*----- Revision history --------------------------------------------------* 
- *
- * $Log: limlee.c,v $
- * Revision 1.8  2001/02/03 11:59:07  mdw
- * Don't use the @pgen@ random number generator for generating primes: it's
- * only for testing them.  Use a caller-supplied one instead.
- *
- * Revision 1.7  2001/01/25 21:40:44  mdw
- * Remove dead code now that the new stepper structure is trustworthy.
- *
- * Revision 1.6  2001/01/25 21:16:20  mdw
- * Boring cosmetic stuff.
- *
- * Revision 1.5  2000/08/18 19:16:51  mdw
- * New stepper interface for constructing Lim-Lee primes.
- *
- * Revision 1.4  2000/08/15 21:45:05  mdw
- * Use the new trial division equipment in pfilt.  This gives a 10%
- * performance improvement in dsa-gen.t.
- *
- * Revision 1.3  2000/07/29 09:58:32  mdw
- * (limlee): Bug fix.  Old versions didn't set the filter step if @ql@ was
- * an exact divisor of @pl@.
- *
- * Revision 1.2  2000/07/26 18:00:00  mdw
- * No footer line!
- *
- * Revision 1.1  2000/07/09 21:30:58  mdw
- * Lim-Lee prime generation.
