#  In particular, it displays a tree-like format of a run level, showing       #
#  all of the services that are installed at that level, and what each         #
#  service's status is (running, stopped, etc.)                                #

#  -a can be used to display all runlevels                                     #
#  -d can be used to display service dependancies                              #
#  -u will display all unassigned services                                     #
