SERVER is a regexp matching the server, and channels is the
list of channels to join.
+If the channel(s) require channel keys for joining, the passwords
+are found via auth-source. For instance, if you use ~/.authinfo
+as your auth-source backend, then put something like the
+following in that file:
+
+machine irc.example.net login \"#fsf\" password sEcReT
+
Customize this variable to set the value for your first connect.
Once you are connected and join and part channels, this alist
keeps track of what channels you are on, and will join them
