Directory Resolution Tokens in the Belief State

During configuration of the config file options, certain string options can make use of directory resolution tokens. These tokens have semantic meaning and are replaced by their respective real values when being read from the configuration file.

Available options that can be utilized are:

  • ${WORKSPACE}: Is replaced by your current Rosbuild/Catkin workspace directory
  • ${PACKAGE package}: Is replaced by the path of the ROS package package
  • ${HOME}: Is replaced by your user's home directory (i.e. /home/user)

Single-word options (like HOME and WORKSPACE) can also be used without the curly brackets.
