I would have just sent this to George, but I thought others might want to comment. I think the -m (menu) option of mprime deserves better press. The only negative about starting mprime with it it is that the menu choice of 6 is needed to start LL checking (or whatever). After that the -d option is active (and I like to see what's going on), and more importantly, ^C does not terminate the program, but brings up the menu again. This allows easy checking of completion dates, and I like to see which way they are moving. For me, it's -m rather than -d from here on out. I apologize to the real mathematicians here who may be offended by something this plebeian.
