This concludes tonight's entertainment. Once I'm sure I haven't destroyed the world with all these changes, I'll import the utilities. Everything should continue to work as before. If it doesn't let me know. Special thanks to Mark Murray for running a test 'make world' for me to shake out the bugs, which, hopefully, I have fixed. (And there was much rejoicing.)
