Banhammer names a function, with lambda list (&REST WORDS):
Ban an IP address from connecting.
Bans can be listed using #banhammer #list
Bans can be lifted using #banhammer #-ip IP-ADDRESS (or hostname)
A ban can be placed with #banhammer #+ip IP-ADDRESS or #banhammer #+ip HOSTNAME or #banhammer #user USERNAME. In the latter case, the user's connected IP address is used. This is expected to be the most common usage.
#banhammer #list #banhammer #user NICKNAME #banhammer #+ip ADDRESS #banhammer #-ip ADDRESS
The first word is a subcommand; one of #+ip, #-ip, #user, or #list. For #+ip, #-ip, or #user, an additional parameter is needed.
