##! The cluster agent boot logic runs in Zeek's supervisor and instructs it to
|
|
##! launch an agent process. The agent's main logic resides in main.zeek,
|
|
##! similarly to other frameworks. The new process will execute that script.
|
|
##!
|
|
##! If the current process is not the Zeek supervisor, this does nothing.
