+<http://librdf.org/ Redland RDF library> bindings. See
+<http://librdf.org/docs/api/index.html the original API> for in-depth
+descriptions.
+
+= Library organization
+
+- Raw bindings are provided by "Redland.LowLevel". Normally they
+  should not be used directly.
+
+- Refined versions (using Haskell types) of those are provided by
+  "Redland.MidLevel". One should still be careful with the allocated
+  resources while using those, for instance by using 'withNew'. A rule
+  of thumb is that whenever you see an 'Initializer', it's a good idea
+  to wrap it into 'withNew'.
+
+- Utility functions and types are provided by "Redland.Util". Those
+  don't strictly correspond to functions of the original API.
+
+
