                          The UNIX Philosophy

Ken Thompson has an automobile which he helped design.  Unlike most
automobiles, it has neither speedometer, nor gas guage, nor any of the
other numerous idiot lights which plague the modern driver.  Rather, if the
driver makes a mistake, a GIANT "?" lights up in the center of the
dashboard.  "The experienced driver," says he, "will usually know 
what's wrong."
