define Package/libseccomp/Default/description
 The libseccomp library provides an easy to use, platform independent, interface
 to the Linux Kernel's syscall filtering mechanism.  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.
