If -tree is specified, the parameter tree structure is displayed. Otherwise the parameters are displayed in a table.
The namespace argument can be used to only display the sub-tree defined by that namespace value.
Only parameters whose advanced setting is less than or equal to the value of the advanced argument will be displayed.
The substr argument can be used to only display parameters whose names contain the specified sub-string.
If the -yml flag is specified, the output will be pure YAML, suitable for parsing.
