| The debug command enables and disables various settings intended to | |
| describe the cli's own behavior. In addition, some of the choices | |
| allow nested invocation of various other tools, intended to debug | |
| various related controller components, for example, 'debug cassandra-cli' | |
| is intended to enter the cassandra cli to view internal database state, | |
| and 'debug bash' is intended to enter a bash subshell to gain access to | |
| the internal environment of the controller. |
