> Doc changes added to the Hadoop/mapreduce/trunk (for Hadoop 0.21 release) need to be
backported to Hadoop-0.20 branch (for Hadoop 0.20.2 release).
> Doc files affected: 
> > streaming.xml
> > mapred_tutorial.xml
> Changes include:
> 1. During the execution of a streaming job, the names of the "mapred" parameters are
transformed. The dots ( . ) become underscores ( _ ). -- (affects streaming doc and m/r tutorial
doc)
> 2. For -files and -archives options, Hadoop now creates symlink with same name as file
(user-defined symlinks, #mysymlink, currently not supported) -- (affects streaming doc)
> 3. Streaming supports streaming command options and generic command options. Generic
options must be placed before streaming options, otherwise command fails. -- (affects streaming
doc)
