- * Version 1.0 : Frederick Roeber : 11 June 1997
- * Version 2.0 : Steve Parkinson : 13 November 1997
- * Version 3.0 : Nelson Bolyard : 22 July 1998
- * Version 3.1 : Nelson Bolyard : 24 May 1999
- *
- * changes in version 2.0:
- * Uses NSPR20
- * Shows structure of SSL negotiation, if enabled.
- *
- * This "proxies" a socket connection (like a socks tunnel), but displays the
- * data is it flies by.
- *
- * In the code, the 'client' socket is the one on the client side of the
- * proxy, and the server socket is on the server side.
