According to Rebecca Thomas and Rik Farrow, authors of UNIX ADMINISTRATION
GUIDE FOR SYSTEM V (ISBN 0-13-942889-5), page 23 (not *exactly* verbatim
but accurate ... BTW this book has many useful tidbits in it) ....

$ crontab -l > /tmp/crontab	# this lists your crontab to a temporary file
[ edit the file /tmp/crontab ... with vi for instance]
$ crontab /tmp/crontab	# forces cron to read the new crontab file

Of course, if you are logged in as root and want to change root's crontab
file you'll see a "#" instead of "$" prompt.
