title: What is the relation between GTK, GTK+ and GTK2?
body: <p>I'm confused by the GTK terminology. According to <a href="http://en.wikipedia.org/wiki/Gtk" rel="noreferrer">Wikipedia</a>, there seem to be bindings to GTK+ that are called GTK (GtkAda) and GTK2 (gtk2hs, Gtk2-Perl).</p>
  
  <p>Could someone clear this up for me?</p>
