+=head1 NAMING CONVENTION
+
+Each and every person in the IRC can be identified by a three-tupel: B<nick>,
+B<user> and B<host>, most often seen as I<nick!user@host>.
+
+The combination of B<user> and B<host> is called an B<ident> here and written
+I<user@host>. The combination of all three parts is called a B<chatter> here,
+though it's rarely used.
+
+A B<name> is the name of the "user" as defined in the F<users.conf>. Therefore,
+the F<users.conf> defines a mapping of B<chatter> -E<gt> B<name>.

+This is normally the step after having parsed all files and before doing any

+
+It does the following: First, it iterates over all chatters and splits them up
+into nicks and idents. If a (user)name is found for the ident it (the ident) is
+replaced with it (the name).
+
+In the second step we iterate over all nicks that have been found and
+determines the most active ident for each nick. After this has been done each
+nick is associated with exactly one ident, but B<not> vice versa.
+
+The final step is to iterate over all idents and determine the most active nick
+for each ident. After some thought you will agree that now each ident exists
+only once and so does every nick.
