IRC proxy for multiple users

 shroudBNC (short: sbnc) is an modular IRC proxy for multiple
 users. Its main features are SSL support for both IRC and client
 connections, client certificates with passwordless authentication,
 IPv6 support, asynchronous dns resolving, built-in flood protection
 and module support.
 shroudBNC comes with many useful Tcl scripts, but you are able to
 write your own, too.
