HOw can I program my own IRC bot?

Often, an IRC bot is deployed as a detached program running from a stable host. It sits on an IRC channel to keep it open and prevents malicious users from taking over the channel. It can be configured to give channel operator status to privileged users when they join the channel, and can provide a unified channel operator list. Many of these features require that the bot be a channel operator. Thus, most IRC bots are run from computers which have long uptimes (generally running a BSD derivative or Linux) and a fast, stable Internet connection. As IRC has become popular with many dial-up users as well, special services have appeared that offer limited user-level access to a stable Linux server with a decent connection. The user may run an IRC bot from this shell account. These services are commonly known as shell providers.
