+MapReduce Commands Guide
+
+%{toc|section=1|fromDepth=2|toDepth=4}
+
+* Overview
+
+  MapReduce commands are invoked by the <<<bin/mapred>>> script. Running the
+  script without any arguments prints the description for all commands.
+
+   Usage: <<<mapred [--config confdir] COMMAND>>>
+
+   MapReduce has an option parsing framework that employs parsing generic
+   options as well as running classes.
+
+*-------------------------+---------------------------------------------------+
+|| COMMAND_OPTIONS        || Description                                      |
+*-------------------------+---------------------------------------------------+
+| --config confdir | Overwrites the default Configuration directory. Default
+|                  | is $\{HADOOP_PREFIX\}/conf.
+*-------------------------+---------------------------------------------------+
+| COMMAND COMMAND_OPTIONS | Various commands with their options are described
+|                         | in the following sections. The commands have been
+|                         | grouped into {{User Commands}} and
+|                         | {{Administration Commands}}.
