Before revision:  We described each package based on a workflow centered around tracking data (i.e.  (x,y,t)), broken down in three stages: pre-processing, post-processing , and analysis( data visualization, track description, path reconstruction, behavioral pattern identification, space use characterization, trajectory simulation and others ) . Supporting documentation is key to the accessibility of a package for users.
