This code performs several functions:
1) Keeps tracks of channel keys. When the key of a channel that you are on changes, the script records that and saves the information in a file. This also saves the key of any channels that you join. Whenever you want to rejoin that channel, but you get an error saying you need a key, the script automatically joins the channel with the previously saved key.
2) If you cannot join a channel because it has mode +R set (registered users only), it automatically joins that channel if you identify yourself (with NickServ) within two minutes.
3) The /chanops command keeps a list of channels in which you have operator status or above. This list is used in case:
3a) You are banned from a channel. The script automatically asks ChanServ to unban you and automatically joins the channel upon being unbanned.
3b) Mode +i is set on a channel. The script automatically asks ChanServ to invite you and automatically joins upon receiving an invite.

Syntax:
/chanops - Views list of channels where the script's "automatically ask ChanServ to unban/invite you in case X happens" function activates
/chanops +<#channel> - Adds channel to list
/chanops -<#channel> - Removes channel from list
/chanops clearall - Clears list

The /clearops list automatically separates itself by network, so you can have ops in two channels named exactly the same on two different networks and be fine.

/chankeys - Opens the data file in Notepad.

This script is great when used in conjunction with an autojoin script of your choosing.
