[Eug-lug] error message

[Mike Cherba]

You gave tar both a -c and a -u option.  those are exclusive options.
you can either create an archive "-c" or update and archive "-u" not
both.
		-Mike

Another effective [debugging] technique is to explain your code to
someone else. This will often cause you to explain the bug to yourself.
Sometimes it takes no more than a few sentences, followed by an
embarrassed "Never mind. I see what's wrong. Sorry to bother you." This
works remarkbly well; you can even use non-programmers as listeners. One
university computer center kept a teddy bear near the help desk.
Students with mysterious bugs were required to explain them to the bear
before they could speak to a human counselor. --- Kernighan & Pike "The
Practice of Programming"
