+/*
+ * swift interface for raw sockets
+ *
+ * Simulates the classic socket syscalls (socket, bind, send, recv).
+ * Implementation uses raw sockets (AF_INET, SOCK_RAW).
+ *
+ * Subsequently, implementation is to be ported into kernel space and
+ * the interface is going to be offered by the Linux syscall API.
+ *
+ * Heavily inspired from GLIBC's <sys/socket.h>
+ * (/usr/include/sys/socket.h).
