Hello Hadoop team. 

Glad to know you put lots of efforts here. I wanna subscribe the dev-mailing list and hope
I will be able to contribute later on. But when I intended to set the Development Environment
in Eclipse(follow with http://wiki.apache.org/hadoop/EclipseEnvironment), I got an error when
I tried to build Hadoop by Ant. The error message said "cannot run program "sed" at line 41".
I went though build.xml and knew it is: 

41: <exec executable="sed" inputstring="${os.name}" 
42:       outputproperty="nonspace.os">
43:     <arg value="s/ /_/g"/>
44:  </exec>

What's program "sed"? how to set it up?

Thank you,
