sl@0:  * This file is only meant to provide a quick
sl@0:  * implementation of the output operator. It is
sl@0:  * provided for test programs that aren't even
sl@0:  * interested in the precision of the results.
sl@0:  * A real progam should define its own operators
sl@0:  * and never include this header.
