+ <p>The socket interface (module) is basically an "thin" layer on top of
+ the OS socket interface. It is assumed that, unless you have special needs,
+ gen_[tcp|udp|sctp] should be sufficent. </p>
+ <p>Note that just because we have a documented and described option,
+ it does <em>not</em> mean that the OS supports it. So its recommended
+ that the user reads the platform specific documentation for the
+ option used. </p>
