====== Simple ROS service examples ======

An example project (ROS node) that serves a virtual "song title database" via ROS can be checked out here:
<code>git clone https://github.com/fairlight1337/ros_service_examples.git</code>
This is just an example for reference purposes.

===== Running the server =====
Running the server using <code>rosrun rosdemo_mp3 mp3_inventory</code> starts the title database server (C++ node, see src/mp3_inventory.cpp). This server serves album lists and according title lists (if requested) of everything stored in `pwd`/albums. So be sure to do <code>roscd rosdemo_mp3</code> before running the mp3_inventory node. The service type for communication is Mp3InventoryService.

===== Running the client(s) =====
The clients request a list of albums from the server. For each entry in this list, they request a list of titles.

For the C++ client, do <code>rosrun rosdemo_mp3 mp3_controller</code>.
For the python client, do <code>rosrun rosdemp_mp3 mp3_controller_python.py</code>.
For the LISP client, from within emacs, do <code>(ros-load:load-system "rosdemo_mp3" :mp3-controller)</code> and then execute <code>(mp3-inventory-interaction)</code>
