Install

 sudo apt-get install ros-indigo-joy-teleop

Run

Did the following to find executables:

The result was joy_leleop.py which lead to the rosrun command below.

 dpkg -L ros-indigo-joy-teleop
     ...
     /opt/ros/indigo/lib/joy_teleop
     /opt/ros/indigo/lib/joy_teleop/joy_teleop.py
     /opt/ros/indigo/lib/joy_teleop/incrementer_server.py
     ...

In the first terminal.

 rosparam set joy_node/dev "/dev/input/js0"
 rosrun joy joy_node

In the second terminal.

 rosrun joy_teleop joy_teleop.py
     [FATAL] [WallTime: 1450196955.332980] no configuration was found, taking node down

This should be fixable using the above reference links. Moving on to the twist package because it may be a better option based on those links.
