The Wraith IRC Bot is an IRC channel management bot based on Eggdrop 1.6.12. TCL scripts and other modules are not supported by Wraith. Wraith has been around since 2003.
A hub is a Wraith bot that does not connect to IRC, but instead allows other bots, known as leafs, to connect to it.
A leaf connects to IRC and to a hub on the botnet.
Wraith keeps an encrypted copy of its configuration file inside of the binary for the bot. To reconfigure the bot you must provide a password. Wraith also only stores an encrypted copy of the user file only on hubs so that nothing is kept locally on the leafs.
