rules. The first rule has a series of sleep and echo commands

intended to run in series. The second and third have just an

echo statement. When make is called in this test, it is given
|
|
the -j option with a value of 4. This tells make that it may
|
|
start up to four jobs simultaneously. In this case, since the

first command is a sleep command, the output of the second

and third commands will appear before the first if indeed
