 <para>The Vala Reference Manual gives details on Vala's syntax and type system, including polymorphism using 
interfaces and type parameters (generics). Vala includes additional code generation routines, for example 
D-Bus inter-process communication and GTK+3 composite templates, these are only referred to in the Attributes 
section. The reference manual does not provide a tutorial for these features.</para>
