+Gtk2Hs suite of libraries. These tools include a modified c2hs binding tool
+that is used to generate FFI declarations, a tool to build a type hierarchy
+that mirrors the C type hierarchy of GObjects found in glib, and a generator
+for signal declarations that are used to call back from C to Haskell. These
+tools are not needed to actually run Gtk2Hs programs.")
