 Example:
   --proctree enabled            | will enable the process tree with default settings (disabled by default).
-  --proctree process=8192       | will cache up to 8192 processes in the tree (LRU cache).
-  --proctree thread=4096        | will cache up to 4096 threads in the tree (LRU cache).

+  --proctree thread-cache=4096  | will cache up to 4096 threads in the tree (LRU cache).
 
 Use comma OR use the flag multiple times to choose multiple options:
-  --proctree process=X,thread=Y
-  --proctree process=X --proctree thread=Y
+  --proctree process-cache=X,thread-cache=Y
+  --proctree process-cache=X --proctree thread-cache=Y
