** License: see jnetlib.h
**
** Usage:
**   1. create a JNL_Listen object with the port and (optionally) the interface
**      to listen on.
**   2. call get_connect() to get any new connections (optionally specifying what
**      buffer sizes the connection should be created with)
**   3. check is_error() to see if an error has occured
**   4. call port() if you forget what port the listener is on.
