+         High level interface to the Linux Kernel's seccomp filter
+         
+         The libseccomp library provides an easy to use, platform independent,
+         interface to the Linux Kernel's syscall filtering mechanism: seccomp.
+         The libseccomp API is designed to abstract away the underlying BPF
+         based syscall filter language and present a more conventional
+         function-call based filtering interface that should be familiar to,
+         and easily adopted by application developers.
