where is hadoop-streaming?

I am new to hadoop. downloaded version 0.20.2 and installed it on local mode.

Run wordcount examples and others successfully, however,
I am trying to run the hadoop-streaming example:

$HADOOP_HOME/bin/hadoop  jar $HADOOP_HOME/hadoop-streaming.jar \
    -input myInputDirs \
    -output myOutputDir \
    -mapper /bin/cat \
    -reducer /bin/wc

But I can NOT find the "hadoop-streaming.jar" anywhere
Exception in thread "main" java.io.IOException: Error opening job jar:
hadoop-streaming.jar
	at org.apache.hadoop.util.RunJar.main(RunJar.java:90)


Please help

Michael

http://wiki.apache.org/hadoop/HadoopStreamingand then edit it to show
the correct location.
