Installation
This section covers software installation of the freetail demo system.
- The freetail program must downloaded from source:  
svn checkout https://swri-ros-pkg.googlecode.com/svn/trunk/ swri-ros-pkg
 - The libraries required for freetail can be downloaded using the rosinstall tool: 
rosinstall -n . swri-ros-pkg/freetail/freetail.rosinstall
NOTE: The rosinstall tool sometimes reports a failure due to a missing ROS package (THIS IS OK). 
The sections below outline special steps that must be taken for specific stacks.
