General concepts

Most of the functions are modelled on the BSD socket API. BSD sockets -are widely supported, portably ("portable" by Unix standards, at least) -available on a variety of systems, and documented. There are some -differences in approach where we have taken advantage of some of the more useful features of Common Lisp - briefly - -
