system call). Then the next occurrences of this option will add or delete the listed system calls
from the set of the filtered system calls, depending of its type and the default action. (For
example, if you have started with an allow list rule for read() and
write(), and right after it add a deny list rule for write(),
then write() will be removed from the set.)

As the number of possible system calls is large, predefined groups of system calls are
provided. A group starts with C<\@> character, followed by name of the set.
