+    >> use Irssi 20011211 qw(signal_add command);
+    
+    Loads the Irssi module, requiring at least version 20011211 and telling
+    it to export signal_add() and command() into our package.
+    This kind of version checking came available in the 20011208-snapshot.
+    Having te Irssi:: subs exported came available in the 20011211-snapshot.
+    
+    >> sub sig_own
+    
+    Warns the user: chatting while having windows switch all the time is
+    foolish, because your text gets sent to whatever window has the focus
+    when you press enter.
+    
+    >> signal_add
+    
+    This was exported into our package, so we can use signal_add() without the
+    "Irssi::" prefix. Since the 20011207 snapshot, you can add multiple signals
+    using a single add_signal(). If you want to do so, use a hash reference
+    (either { foo => bar, foo2 => bar2 } or \%hash).
+    
+    >> sub { ... }
+    >> \&subname
+    
+    These are references to subs(code). The first one is a reference to an
+    anonymous sub, the second one refers to a named one. Anonymous code
+    references allow for easy placement of oneliners :)
+    Irssi understands codereferences since the 20011207 snapshot.
+    Using references is better than having a string with the function name,
+    imho.
