Overview

Package irc defines types to be used by most other packages in the ultimateq system. It is small and comprised mostly of helper like types and constants.

Constants

	INFO_RFC         = "RFC"
	INFO_IRCD        = "IRCD"

	INFO_AWAYLEN     = "AWAYLEN"
	INFO_KICKLEN     = "KICKLEN"
	INFO_MODES       = "MODES"
)

These constants are the mappings from the 004 and 005 events to their respective spots inside the NetworkInfo type.

IRC Reply and Error Events. These are sent in reply to a previous event.

Pseudo Events, these events are not real events defined by the irc protocol but the bot provides them to allow for additional events to be handled such as connect or disconnects which the irc protocol has no protocol defined for.
